A circular sheet with radius 36 cm is divided into four equal sectors and one of them into a cone.
What is the radius of the cone?

A right circular cone of height 8.4cm and the radius of its base is 2.1cm. It is melted and recast into a sphere. Find the radius of the sphere.

A right circular cone 3.6 cm high with base radius 1.6 cm is melted and recast into another cone of base radius 1.2 cm. then its height is

If the height of a cone is equal to diameter of its base, then what is the volume of cone ?

Find the volume of the right circular cone with radius 6 cm, height 7 cm

The volume of a right circular cone is 9856 cm. If the diameter of the base is 28 cm. Find (i) the height of the cone (ii) slant height of the cone (iii) curved surface area of the cone

A cylinder and cone are of same height and base radius. Find the ratio of their volume.
