The volume of a sphere is 32
3
π cubic centimeters. What is the radius?

Sphere V = 4
3
πr3

1. Substitute 32
3
into the volume formula for V: 32
3
π = 4
3
πr3

2. Multiply both sides of the equation by 3
4
: 8π = πr3

3. Divide both sides of the equation by π. 8 = r3

4. Take the cube root of both sides: 3√8 = r

The radius of the sphere is
cm.
