If the radius of the hemisphere is 21 cm, then find its volume.

Volume of a sphere is equal to the volume of a hemisphere. If the radius of the hemisphere is root3 32 cm, then the radius of the sphere is equal to

A solid wooden toy is in the shape of a right circular cone mounted on a hemisphere. If the radius of the hemisphere is 4.2 cm and the total height of the toy is 10.2 cm, find its volume.

A toy is in the form of a hemisphere surmounted by a right circular cone of same base radius. If the radius of the base of the cone is 21 cm and its volume is 2/3 volume of hemisphere, calculate the height of the cone and the total curved surface area of the toy.

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
