A circular flower bed is 19m in diameter and has a circular sidewalk around it that is 3m wide. Find the area of the sidewalk in square meters. Use 3.14 for pi.
The area of the sidewalk ____ m².
Area of the circular sidewalk around flowerbed is 207.24 m² .
What is area?Area is the amount of space occupied by a two-dimensional shape. That is, it is a quantity that measures the number of unit squares that cover the surface of a closed figure. Standard area unit is square unit.
Given,
Diameter of flowerbed = 19m
radius = diameter/2 = 19/2 = 9.5 m
Area of flower bed A
= πr²
= 3.14(9.5)²
= 3.14(90.25)
= 283.385 m²
width of the sidewalk = 3m
radius of flower bed with sidewalk = 9.5 + 3 = 12.5m
Area of flower bed with sidewalk A'
= 3.14(12.5)²
= 3.14(156.25)
= 490.625 m²
Area of the sidewalk
= A' - A
= 490.625 - 283.385
= 207.24 m²
Hence, 207.24 m² is area of the circular sidewalk around flowerbed.

Quadrilateral ABCD is a parallelogram. If adjacent angles are congruent, which statement must be true?
Answer:
Step-by-step explanation:
A parallelogram is a shape that has two sets of parallel. There are a number of examples of parallelogram including but not limited to, square, rectangle, rhombus etc
From the question, the answer is, the shape is a rectangle. This is because the question says that the shape has its adjacent angles congruent, this means that they are supplementary(i.e they add up to 180). A rectangle is the one who fits the perfect description
A rectangle in the coordinate plane has vertices at (-1, 6), (-1, 2), (4, 2), and (4, 6). The perimeter of the rectangle is Choose... units. The area of the rectangle is Choose... square units.
Answer:
perimeter = 18 units
area = 20 square units.
Step-by-step explanation:
We know that a rectangle is defined by two measures, length L, and width W.
Such that the perimeter is given by:
P = 2*(L + W)
and the area is given by:
A = L*W
Here we know that the vertices of or rectangle are:
(-1, 6)
(-1, 2)
(4, 2)
(4, 6)
Here you can see that we have just two different values of x (-1 and 4) and two different values of y (6 and 2)
So we can define the length L as the difference between the two different values of x:
L = 4 - (-1) = 4 + 1 = 5 units
And the width as the difference between the two different values of y:
W = 6 - 2 = 4 units
A graph of the rectangle can be seen below, to see why I choose to define the length and width in this way.
Now that we know the measures of our rectangle, and using the above formulas for perimeter and area, we get:
P = 2*(W + L) = 2*(5 + 4) = 18 units
A = W*L = 5*4 = 20 square units
A square pyramid is sliced horizontally, parallel to its base. What shape would represent
its cross section?
PLLEASEEEEEEEEEEEEEEEEE HELPPPPPPPPPP!!!! ill brainlist/ rate u 5 star.
A ramp is used so a trolley can be wheeled on to a platform.
The cross-section of the ramp is drawn as a right-angled triangle with
the unknown height labelled as x.
1 Is the unknown length in this triangle (shown as x) the length of
the hypotenuse? Explain ur answer.
Answer:
The hypotenuse is sqrt ( 2x^2)
Step-by-step explanation:
Given a right angled triangle, we can find the hypotenuse of a triangle using the Pythagorean theorem which says that c^2 = a^2 + b^2, where a is the length, b is the perpendicular height and c is the hypotenuse. The length of the triangle (l) is x and the height of the triangle is also x. By substituting the values,
c^2 = x^2 + x^2 = 2x^ 2
There are two possible answers to c but the hypotenuse cannot be negative.
Hence,
c = Sqrt (2x^2)

O ZBOC= 40
O ZBOC = 10
O ZBOC= 50°
O ZBOC= 90°
Answer:
∠ BOC = 40°
Step-by-step explanation:
∠ AOC = 90° , then
5x + 2x + 20 = 90
7x + 20 = 90 ( subtract 20 from both sides )
7x = 70 ( divide both sides by 7 )
x = 10
Then
∠ BOC = 2x + 20 = 2(10) + 20 = 20 + 20 = 40°

What do you think the hypervolume of a hypercube is? Why?
Answer:
[tex]a^4[/tex] Where (a) is the side length of the hypercube
Step-by-step explanation:
A dimension can be simply defined as a direction in which matter can move it.
We live in a 3-dimensional world, matter can move in three basic directions. The formula for finding the volume of a cube is the following: ([tex]a^3[/tex]). In the second dimension, a flat world, the area for the volume of a square is as follows: ([tex]a^2[/tex]). However, a hypercube is a paradox, as it exists in 4-dimensions, thus it cannot exist in our world. However, scientists propose "String theory" which requires that matter can move in more directs than the (3) we know of in our world. In essence, there can be more than 3 dimensions. A hypercube is the 4-dimensional version of a cube. If it follows the area pattern that a square-object follows in all preceding dimensions then the area of a hypercube is ([tex]a^4[/tex]).
Bear in mind that the area patter for a square-object is generally the following:
[tex]a^n[/tex]
Where (a) is the side length of the square-object
(n) is the dimension the object is in.
Please keep in mind, this answer was written in the June of 2021, as science keeps progressing and new discoveries are made, this theory can be disproven. Therefore, this answer might be considered correct now, but it can be proven incorrect in the future.
The Earth rotates every 24 hr and as diameter of 7, 926 mi. If you're standing on the equator, how fast are you traveling in miles per hour (mph)?
The more accurate value is 1037.51097384802
Round that however you need to.
=======================================
Explanation:
We need the circumference of the equator. Think of the equator as the largest possible circle (or belt) to fit around the earth.
C = pi*d
C = pi*7926
C = 7926pi
C = 24,900.2633723527
In 24 hours, a person at the equator travels roughly 24,900.2633723527 miles since the earth does a full rotation in this timespan.
Divide the two quantities distance over time to get the speed
rate = distance/time
rate = (24,900.2633723527 miles)/(24 hours)
rate = ( (24,900.2633723527)/(24) ) miles per hour
rate = 1,037.51097384802
rate = 1038 mph
I'm rounding to 4 sig figs since the diameter is given to be in four sig figs.
This speed of roughly 1038 mph is a linear speed and not an angular speed.
-----------------------------
Extra info (optional section)
Upon further research, I found an article from NASA JPL (jet propulsion laboratory) which states quote:
"To make one complete rotation in 24 hours, a point near the equator of the Earth must move at close to 1000 miles per hour (1600 km/hr)"
Their figure of 1000 mph seems to be a rough estimate, more or less. It's fairly close to the 1038 figure we got earlier.

have a great day!!
Answer:
I believe it would be 1570.
Step-by-step explanation:
The formula to find the volume of a cylinder is:
V = pi • r² • h
The diameter is usually 2x the radius:
20m ÷ 2 = 10
The radius would be 10m.
3.14 • 10² • 5 = 1570 cubic m

For the equation =7−12 which value represents the slope of a line perpendicular to the equation?
Answer:
69
Step-by-step explanation:
Graph the second equation to find the solution of the system of equations.
y = –x,
y = 2x + 6
What is the point of intersection
Answer:
So the point of intersection would be -x=2x+6
and then we'll subtract 2x on both sides and get -3x=6
this will result in x=-2
Then we'll substitute that into y=-x, so y=2
Therefore the point of intersection is (-2,2)
Hope I helped, have a nice day :)

For a science project, Joseph launches a model rocket. The function "h(s)=-3s^2+6s+45 represents the height in feet of the rocket after s seconds. It will take the rocket ___ second(s) to reach its maximum height. A - 1 B - 3 C - 5 D - 45 E - 48
Answer:
t = 1 s to reach its maximum height.
Step-by-step explanation:
The function that represents the height of the rocket after s seconds is given by :
[tex]h(s)=-3s^2+6s+45[/tex] ...(1)
For maximum height,
[tex]h'(s)=0\\\\-6s+6=0\\\\s=1[/tex]
It is the time the rocket will take. So, the ball will take 1 second to reach its maximum height.
What is the smallest of 3 consecutive odd numbers if the product of the smaller two integers is 3 less than 6 times the largest integer?
Answer:
7,9,11
Step-by-step explanation:
Let first number is x, second number is (x+2) and third number is (x+4).
ATQ,
The product of the smaller two integers is 3 less than 6 times the largest integer.
x(x+2) = 6(x+4)-3
x² + 2x = 6x+24-3
x² + 2x = 6x+21
x² + 2x -6x -21=0
x²-4x -21=0
It is a quadratic equation whose solution is :
x = -3 and x = 7
First number = 7
Second number = 9
Third number = 11
Hence, this is the required ssolution.
Find the equation of a line that passes through the point (3,6)
with slope 2.
Answer:
y = 2x
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2 , then
y = 2x + c ← is the partial equation
To find c substitute (3, 6) into the partial equation
6 = 6 + c ⇒ c = 6 - 6 = 0
y = 2x ← equation of line
The equation of line that passes through the point (3,6) with slope 2 is;
⇒ y = 2x
Given that;
The point is (3, 6)
The slope of line = 2
We have to find the equation of a line that passes through the point (3,6) with slope 2.
What is equation of line?
The equation of line that passes through the point (x₁, y₁) with slope m is;
y - y₁ = m (x - x₁)
The point is (3, 6)
The slope of line = 2
The equation of line that passes through the point (x₁, y₁) = (3,6)
with slope(m) = 2 is;
y - y₁ = m (x - x₁)
y - 6 = 2 (x - 3)
y - 6 = 2x - 6
Add 6 on both sides;
y = 2x
Hence, The equation of line that passes through the point (3,6) with slope(m) 2 is;
⇒ y = 2x
