A sphere just fits in a cylindrical vessel and the height of the cylindrical vessel is the same as the height of the spere . Show that the curved surface area of the cylinder is the same as the curved surface area of the sphere .

Prove that the surface area of a sphere is equal to the curved surface area of the circumscribed cylinder.

The ratio of the surface area of a sphere and the curved surface area of the cylinder circumscribing the sphere is

The curved surface area of a cylinder with radius 2cm and height 7 cm will be :

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 __________.

Curved surface area of a cylinder of radius h and height r is _______.

A cylinder of height 2x is circumscribed by a sphere of radius 2x such that the circular ends of the cylinder are two small circles on the sphere. What is the ratio of the curved surface area of the cylinder to the surface area of the sphere?

A right circular cylinder circumscribes a sphere of radius r.Find the ratio of the surface area of the sphere to the curved surface area of the cylinder.

As shown in the adjacent figure, a sphere is placed in a cylinder. It touches the top, bottom and the curved surface of the cylinder. If radius of the base of the cylinder is 'r', (i) what is ratio of the radii of the sphere and the cylinder? (ii)what is the ratio of the curved surface area of the cylinder and the surface area of the sphere? (iii) what is the ratio of the volumes of the cylinder and the sphere?

If radius is r and height is h, then find curved surface area of cylinder.
