The length of radius of base of a solid right circular cone is equal to the length of radius of a solid sphere . If the volume of the sphere is 2 times the volume of the cone , then find the ratio of the height and radius of base of the cone .

The radius of a sphere is equal to the radius of the base of a right circular cone, and the volume of the sphere is double the volume of the cone. The ratio of the height of the cone to the radius of its base is

The radius of the base of a solid right circular cone is 8 cm and its height is 15 cm. The total surface area of the cone is:

If the length of the radius of the base of a right circular cone be halved and its height be doubled, then the volume remains same.

The height and radius of base of a right circular cylinder are equal . A equal circular cone of same radius is made by melting this cylnder , if the volume of the cone is (2sqrt(2))/3 times the volume of cylinder , then how many times the slant height of the cone will be than the radius ?

If the radius of the base of a right circular cone by halved and its height be doubled , then the volume of the cone remains the same.

A solid metallic right circular cone of height 30cm and radius of the base 12 cm is melted and two solid spheres formed from it. If the volume of one of the sphere is 8 times that of the other find the radius of the smaller sphere.

A solid metallic right circular cone of height 30cm and radius of the base 12 cm is melted and two solid spheres formed from it. If the volume of one of the sphere is 8 times that of the other find the radius of the smaller sphere.

The base of a right circular cone has the same radius a as that of a sphere. Both the sphere and the cone have the same volume. Height of the cone is____

The ratio of the radius of base of a right circular cone and its height is 3:4 . If the volume of the cone be 301(5)/(7)c c , then what will be the height of the cone ?

The lengths of radii of a solid right crcular cone and a solid sphere are equal. If their - volumes be also equal, then find the ratio of the radius of the sphere and the height of the cone.
