The radius and height of a right circular cone.

The radius and height of a right circular cone are in the ratio 5 : 12. If its volume is 2512 cm , find its slant height. (Take π = 3.14).

Solution:

Let radius of cone (r) = 5x
then height (h) = 12x

A cone and a cylinder are of the same height. If diameters of their bases are in the ratio 3 : 2, find the ratio of their volumes.

Solution:

Let height of cone and cylinder = h
Diameter of the base of cone = 3x
Diameter of base of cylinder = 2x
