There are two right circular cones of equal height. The radius of base of one cone is half of the radius of the other. Find the ratio of their volumes.

A solid metallic right cone is melted and some solid right circular cylinders are made. If the radius of base of each cylinder is half the radius of cone and the height of each cylinder is one third the height of the cone, then the number of cylinders formed are.

The heights of two right circular cones are in the ratio 1:2 and the perimeters of their bases are in the ratio 3:4. Find the ratio of their volumes.

A solid sphere is melted and recast into a right circular cone with a base radius equal to the radius of the sphere . What is the ratio of the height and radius of the cone so formed ?
