Work out the area of a circle whose diameter is equal to 14 cm.
Give your answer correct to 2 decimal places.
cm?
help
Given:
The diameter of the circle = 14 cm
To find:
The area of the circle.
Solution:
We have,
Diameter of the circle = 14 cm
We know that the radius of the circle is half of its diameter. So,
[tex]r=\dfrac{14}{2}[/tex]
[tex]r=7\text{ cm}[/tex]
The area of a circle is:
[tex]A=\pi r^2[/tex]
Substituting [tex]\pi=\dfrac{22}{7}, r=7[/tex] in the above formula, we get
[tex]A=\dfrac{22}{7}\times (7)^2[/tex]
[tex]A=22\times 7[/tex]
[tex]A=154[/tex]
Therefore, the area of the circle is 154 square cm.
Find the volume of each figure. Round to the nearest tenth. Plz show work
use 3.14 for π round to the nearest tenth
Answer:
A=4pi(r)^2
A=4pi(5)2
A=4pi25
A=314.16 rounds to 314.6 m
Volume=4/3pi(r)^3
volume=4/3pi(5)^3
volume=4/3pi(125)
volume=523.59 rounds to 523.6 m
hope this helps
have a good day :)

The vertices of a triangle are \large A\left(-4,-2\right), \large B\left(1,3\right) and \large C\left(4,-2\right).
Answer:
[tex]Area = 20[/tex]
Step-by-step explanation:
Given
[tex]\large A\left(-4,-2\right), \large B\left(1,3\right), \large C\left(4,-2\right).[/tex]
Required
The area
The area of a triangle is:
[tex]Area = \frac{1}{2}|A_x(B_y - C_y) + B_x(C_y - A_y) + C_x(A_y - B_y)|[/tex]
So, we have:
[tex]Area = \frac{1}{2}|-4(3 - -2) + 1(-2 - -2) + 4(-2 - 3)|[/tex]
[tex]Area = \frac{1}{2}|-4*5 + 1*0 + 4*-5|[/tex]
[tex]Area = \frac{1}{2}|-40|[/tex]
[tex]Area = \frac{1}{2}*40[/tex]
[tex]Area = 20[/tex]

Find the length of the third side. 20 24
Answer:
Hypotenuse (Third side) = 31.24
Step-by-step explanation:
20² + 24² = Hypotenuse²
400 + 576 = Hypotenuse²
976 = Hypotenuse²
[tex]\sqrt{976}[/tex] = Hypotenuse
31.24 = Hypotenuse
Therefore, the measure of the third side would be: 31.24

every parallelogram is a square?
every rectangle with four congruent sides is a square?
every rectangle is a quadrilateral?
every quadrilateral is a rectangle?
Answer:
every parallelogram is a square? False
every rectangle with four congruent sides is a square? True
every rectangle is a quadrilateral? True
every quadrilateral is a rectangle? False
Step-by-step explanation:
every parallelogram is a square?
A parallelogram has two opposite pairs of parallel lines and opposite congruent sides. A square needs to have 4 right angles and all sides need to be equal. In the restrictions of a parallelogram, these cannot be concluded, therefore parallelogram are not always squares.
every rectangle with four congruent sides is a square?
Square require 4 congruent sides and 4 right angles. Rectangles already have 4 right angles. If you add 4 congruent sides to the mix, it means that these rectangles are always squares.
every rectangle is a quadrilateral?
A quadrilateral is defined by a shape having 4 sides. Rectangles have 4 sides, so they fit into the category of quadrilaterals.
every quadrilateral is a rectangle?
A quadrilateral is a just a shape with four sides. We do not know if it has 4 right angles, so not every quadrilateral is a rectangle.

What is the slope of the line with the equation y +2 = -3(x – 7)?
OA.m = -3
O B. m = 3
O C. m = 2
O D. m = -7
Answer:
A.m = -3
Step-by-step explanation:
This equation is written in point slope form
y-y1 = m(x-x1)
y +2 = -3(x – 7)
y - -2 = -3(x – 7)
The slope is -3 and the point is (7, -2)
Write the equation of the parabola in vertex form.

Bradley wants to build a shop in his backyard. He knows the shop will be a rectangular shaped building. He wants the length of the shop to be the expression of 3x + 23 and the width to be 2x + 17. Write a trinomial that would represent the area of the shop. Show your work
Answer:
A = 6x² + 97x + 391
Step-by-step explanation:
Given that,
The length of the shop, l = (3x+23)
The width of the shop, b = (2x+17)
The expression for the area of the shop is given by :
A = lb
Put all the values,
A = (3x+23) × (2x+17)
= 6x² +51x+46x +391
= 6x² + 97x + 391
Hence, the expression for the area of the shop is equal to 6x² + 97x + 391.
Solve for x. -9 = 2x + 3

Barry drew a scale drawing of an office building. The scale of the drawing was 3
inches = 2 feet. A desk is 6 feet long in real life. How long is the desk in the
drawing?
Answer:
3inches=2feet and
Xinches=6feet so Cross multiply
2X=18 divided both sides by 2
X=9inches therefore
