Radius the radius OA of the base circle is called the radius of the cone.

Radius the radius of the circular bases is called the radius of the cylinder.

The height of a cone is equal to the radius of its base. The radius of a sphere is equal to the radius of the base of the cone. The ratio of the volume of the cone to the volume of the sphere is

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.

The area of the base of a cone is 616 sq.cm.Then find the radius of the cone.

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 ?

If the height of a given cone be doubled and radius of the base remains the same, the ratio of the volume of the given cone of that of the second cone will be

If the height of a cone is half the radius of a sphere then the radius of the base of the cone, which has the same volume as a sphere of radius 7 cm is :

A sector of a circle of radius 6 cm and central angle 30^(@) is folded into a cone such that the radius of the sector becomes the slant height of the cone. What is the radius of the base of the cone thus formed?
