If the height of a come is doubled, then its volume is increased by?

Original volume = 1/3 πr 2 h; New volume = 1/3 πr 2 (2h) = 2/3πr 2 h Required increased % = [πr 2 h/3]/[πr 2 h/3] x 100% = 100%

Question

Accepted Answer

Original volume = 1/3 πr²h;
New volume = 1/3 πr²(2h) = 2/3πr²h
Required increased % = [πr²h/3]/[πr²h/3] x 100%
= 100%
