Question

The volume of a sphere is 36π in³. What is the radius of the sphere?

Answer 1

36pi = 4/3 * pi * r^3
27 = r^3
r = 3 in

Answer 2

The equation for volume of a sphere is (4/3)πr^3, and you want to solve for r, so:
(4/3)πr^3 = 36π
÷ 4/3
πr^3 = 27π
÷ π
r^3 = 27
(cube root)
r = 3

So the radius is 3, I hope this helps!
