Write the formula for volume of the frustum of the Cone

Volume of a Frustum

Derive the formula for the volume of right circular cone with radius r and height h.

The radii of the frustum of a right circular cone are in the ratio 2 : 1. What is the ratio of the volume of the frustum of the cone to that of the whole cone ?

Volume of frustum=____.

Volume of frustum of right circular cone

If r_1 and r_2 denote the radii of the circular bases of the frustum of a cone such that r_1> r_2 , then write the ratio of the height of the cone of which the frustum is a part to the height of the frustum.
