If a hemisphere has a curved surface area of 175cm² its radius is

A small body of mass m slides down from the top of a hemisphere of radius R. The surface of block and hemisphere are frictionless. The height at which the body loses contact with the surface of the sp

a solid cylinder has total surface area of 462 cm2. If total surface area of the cylinder is thrice of its curved surface are then the volume of the cylinder is

The surface area of a sphere is same as the curved surface area of a right circular cylinder whose height and diameter are 12 cm each. The radius of the sphere is:

The curved surface area of a cylindrical pillar is 264 m2 and its volume is 924 m3. Find the ratio of its diameter to its height

The curved surface area of a cylindrical pillar is 264 sq.m and its volume is 924 cub.m. Find the ratio of its diameter to its height

A hemisphere and a cone have equal bases. If their heights are also equal, then the ratio of their curved surface will be :
