Front

What is the difference between radius and diameter?

Back

The radius is half the length of the diameter. The diameter is the distance across the sphere through its center.

Front

If the radius of a sphere is doubled, how does the volume change?

Back

If the radius is doubled, the volume increases by a factor of 8, since volume is proportional to the cube of the radius.
