Question

PLEASE HELP ME! I DON'T UNDERSTAND HOW TO SOLVE THIS!!

If the volume is 64π how would i solve this equation for r?

V=4/3πr^3

Answer 1

Explanation:

V = 4/3 pi r^3

64 pi = 4/3 pi r^3 divide both sides of the equation by pi :

64 = 4/3 r^3 multiply both sides by 3/4

3/4 * 64 = r^3 simplify a bit

48 = r^3 take cube root of both sides

r = 3.63 units
