Hey I have the formula for this equation but I don't understand mind giving me a hand

Answer:
See example below
Step-by-step explanation:
The volume of a sphere is the amount of space inside it. A sphere is any round shape 3d object like a ball. Every sphere has a radius from its center to the edge. Using the radius in the formula, gives the volume.
As there is no problem in the picture, here is an example:
Find the volume of a sphere with radius 4 inches.
Substitute r = 4 into [tex]V = \frac{4}{3} \pi r^3[/tex].
[tex]V = \frac{4}{3} \pi r^3\\V = \frac{4}{3} \pi 4^3\\V = \frac{4}{3} \pi *64\\V = \frac{4*64}{3} \pi\\V = \frac{256}{3} \pi\\V = 84.333 (3.14)\\V = 267.94 in^3[/tex]
