Question

in a cylinder the radius is halfed and the hight is doubled find the volume​

Answer 1

Explanation:

Let “A” - be the volume of the cylinder with radius “r” and height”h”. Then A= πr²h ….. Eqn-1. So if the RADIUS IS HALVED AND HEIGHT IS DOUBLED, THE VOLUME IS HALVED.

Answer 2

Explanation:

Let the radius and height of the cylinder be 14 cm and 20 cm respectively. Therefore, the original volume will be as follows. Therefore, in a cylinder, if the radius is halved and the height is doubled, then the volume will be halved
