The radius and height of the base of a cone are equal. Its volume and the volume of a sphere of the same radius...

A sphere, a cylinder and a cone having same radius and height of cylinder and cone are equal to diameter of sphere. Ratio of their volume are

If the height and the radius of a cone are doubled, the volume of the cone becomes

The volume of a right circular cone, whose radius of the base is same as one-third of its altitude, and the volume of a sphere are equal. The ratio of the radius of the cone to the radius of the sphere is:

The radius of base of a cone is r and height is h. Find its volume.

A toy is in the form of a hemisphere surmounted by a right circular cone of the same base radius as that of the hemisphere. If the radius of the base of the cone is 21cm and its volume is 2/3 of the volume of the hemisphere, calculate the height of the cone and the surface area of the toy. (U s epi=(22)/7)dot

The volume of a right circular cone, whose radius of the base is the same as five-ninth of its altitude and the volume of a sphere are equal. The ratio of the radii of the cone to the sphere is:

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 and height of a cylinder are equal. If the radius of the sphere is equal to the height of the cylinder, then the ratio of the rates of increase of the volume of the sphere and the volume of the cylinder, is
