1.	If the height of a cylinder is doubled and radius remains the same, then volume will be A. doubledB. halvedC. sameD. four times
Answer» Correct option is A. doubled Let radius of cylinder = r Let height of cylinder = h So, volume of cylinder = πr²h New radius = r New height = 2h So, volume becomes = πr²× 2h = 2πr²h It becomes DOUBLED.

If the height of a cylinder is doubled and radius remains the same, then volume will be A. doubledB. halvedC. sameD. four times

Answer»

Correct option is A. doubled

Let radius of cylinder = r

Let height of cylinder = h

So, volume of cylinder = πr²h

New radius = r

New height = 2h

So,

volume becomes = πr²× 2h = 2πr²h

It becomes DOUBLED.
