Question

(a)
(iv) In a right circular cylinder, if the length of radius is halved and height is doubled,
volume of cylinder will be
1​

Answer 1

Answer:

The formula for volume of right circular cylinder is πr²h

So , new r will be r/2 and new h will be 2h

New volume = π(r/2)²2h

= πr²/4 * 2h = πr²h/2

Original = πr²h    New = πr²h/2

Therefore, the volume gets halved

Hope this helps...
