Write the number of surfaces of right circular cylinder

A rectangular sheet of paper 30 c m\ x\ 18 c m can be transformed into the curved surface of a right circular cylinder in two ways i.e., either by rolling the paper along its length or by rolling it along its breadth. Find the ratio of the volumes of the two cylinders thus formed.

Show that the surface area of a sphere is the same as that of the lateral surface of a right circular cylinder that just encloses the sphere.

Show that the surface area of a sphere is the same as that of the lateral surface of a right circular cylinder that just encloses the sphere.

A solid toy is in the form of a hemisphere surmounted by a right circular cone. The height of the cone is 2 cm and the diameter of the base is 4 cm. Determine the volume of the toy. If a right circular cylinder circumscribes the toy, find the difference of the volumes of the cylinder and the toy.

The ratio between the curved surface area and the total surface area of a right circular cylinder is 1:2. Find the ratio between the height and radius of the cylinder.
