The volume of a sphere is 3 n cubic centimeters. What is the radius?
Sphere V =
올가
3
32
1. Substitute into the volume formula for V:
2. Multiply both sides of the equation by :
8л = лаз
3. Divide both sides of the equation by n.
8 = 3
4 Take the cube root of both sides:
3 =
3.78 = r
The radius of the sphere is
cm.
