What is the volume of air between the cone and cylinder?

Question

A cone fits inside a cylinder so that they share a base and have the same height. The radius of the base is 4 in. and the height of the cylinder and cone is 13 in. What is the volume of air between the cone and cylinder?

Answer 1

VOLUME OF CYLINDER = PI•R²•H

VOLUME OF CONE = (1/3)PI•R²•H

so the difference must be (2/3)PI•R²•H.
