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

If the radius of a sphere ia equal to the height and radius of the cylinder then the ratio of the rates of increases of the volumes of the sphere and cylinder is

The ratio of the volumes of a right circular cylinder and a sphere is 3:2. If the radius of the sphere is double the radius of the cylinder, then find the ratio of area of whole surface of the sphere and the cylinder

A sphere and the base of a cylinder have equal radii. The diameter of the sphere is equal to the height of the cylinder. The ratio of the curved surface are of the cylinder and surface area of the sphere is __________.

The radius of a sphere and a circular cylinder is r. If their volumes are equal, the height of the cylinder will be

If the radius and the perpendicular height of a cone and cylinder is equal then write the ratio of their volumes.

If the radius of a cylinder and hemisphere is same and their height is also equal then the ratio of their volume is

If the radius and the perpendicular height of a cone and cylinder is equal then write the ratio of their volumes.
