Volume of Spheres Examples

Example 1

Find the volume of a sphere with a diameter of 20 millimeters.

Example 2

Weebles wobble but they don't fall down. If Mr. Weebleton, the mayor of Weebletown, is 14 centimeters tall and has a radius of 4 centimeters, how big is he? All Weebles have this basic shape.

Example 3

If the diameter of the moon is 3476 kilometers, find its volume. If 1 km3 of cheese feeds 100 people and there are 8 billion people on Earth, could the moon feed the whole world? Assume that the moon is a perfect sphere, that it's made entirely of cheese, and that no one is lactose-intolerant.
