What is the diameter of a sphere with a volume of 72 in”, to the nearest tenth of an
inch?
The required diameter of the sphere where the volume is 72 inches is 5.2 inches respectively.
What is a sphere?A sphere is a geometrical object that resembles a two-dimensional circle in three dimensions. In three-dimensional space, a sphere is a collection of points that are all located at the same distance from a single point.
The radius of the sphere is denoted by the letter r, and the specified point represents its center.
The sphere is a three-dimensional shape that is sometimes referred to as a circle's second cousin.
A sphere is a solid shape that is circular, without borders.
Balloons, toy balls, and even light bulbs are examples of objects with sphere shapes.
So, the volume of the sphere formula is:
4/3πr³
We know that the volume is 72 inches.
Then calculate as follows:
72 = 4/3πr³
r³ = 72*3/4π
r = 2.58 (Approx)
Rounding off: 2.6 inches
Then the diameter would be:
2.6 * 2 = 5.2 inches
Therefore, the required diameter of the sphere where the volume is 72 inches is 5.2 inches respectively.

Answer:
[tex]s=20[/tex]
Step-by-step explanation:
By the Exterior Angle Theorem, we know that the exterior angle is equal to the sum of the two, opposite interior angles.
In other words:
[tex]4s=(3s-20)+(2s)[/tex]
Solve for s. Combine like terms:
[tex]4s=5s-20[/tex]
Subtract 5s from both sides:
[tex]-s=-20[/tex]
And divide both sides by negative one. Therefore:
[tex]s=20[/tex]

Cameron sponsored a fundraiser that 582 people attended. He raised 6,480. He charged $15 for balcony seats and $10 for ground seats. How many people bought balcony seats (b) and how many bought ground seats (g)?
15b + 10g = 6,480
b + g = 582
Answer:
132 people bought balcony seats and 450 people bought ground seats.
Step-by-step explanation:
We want to solve the system of equations:
[tex]\left\{ \begin{array}{ll} 15b+10g=6480 \\ b+g=582 \end{array} \right[/tex]
We can solve this by using substitution. From the second equation, we can subtract b from both sides:
[tex]g=582-b[/tex]
In the first equation, we can divide both sides by five:
[tex]3b+2g=1296[/tex]
Substitute:
[tex]3b+2(582-b)=1296[/tex]
Distribute:
[tex]3b+1164-2b=1296[/tex]
Simplify:
[tex]b+1164=1296[/tex]
Solve for b:
[tex]b=132[/tex]
Using the modified equation again, substitute:
[tex]g=582-(132)[/tex]
Evaluate:
[tex]g=450[/tex]
Therefore, 132 people bought balcony seats and 450 people bought ground seats.

Given:
The two points C(2,-1) and D(5,3) on a coordinate plane.
To find:
The distance from C to D.
Solution:
The distance between two points is defined by the distance formula.
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The two points are C(2,-1) and D(5,3). Using the distance formula, we get
[tex]CD=\sqrt{(5-2)^2+(3-(-1))^2}[/tex]
[tex]CD=\sqrt{(3)^2+(3+1)^2}[/tex]
[tex]CD=\sqrt{(3)^2+4^2}[/tex]
On further simplification, we get
[tex]CD=\sqrt{9+16}[/tex]
[tex]CD=\sqrt{25}[/tex]
[tex]CD=5[/tex]
The distance from point C to D is 5 units. Therefore, the correct option is A.
