The lateral surface of a cylinder is equal to the curved surface of a come. If the radius be the same, find the ratio of the height of the cylinder and slant height of the cone.

Text Solution

Verified by Experts

The lateral surface of a cylinder is equal to the curved surface of a cone
so `2pirh=pirl`
(since given radius of both are equal )
so, `h/l=1/2`
