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.

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.

If the height of the right circular cone is increased by 200% and the radius of the base is reduced by 50%, then the volume of the cone

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 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?
