Question

radius of a cyclinder is r and the height is h.. find the change in the volume if the height is doubled

Answer 1

given,

measurements of original cylinder

Radius = r
Height = h

Volume = πr²h

If ,
height is doubled,

height = 2h
radius = r

Volume = πr²2h

so,
the change in volume

$= \frac{\pi {}^{} {r {}^{2} h}^{} }{\pi {r}^{2}2h }$
cancelling the π, r² and h,

we are left with 1/2

so,

The new volume will be 2 times that of the previous volume or

The original volume will be half of the new volume .

Answer 2

The volume of a cylinder is 2 pie rh
So if height is doubled i. e., 2h
Volume will be 4 pie rh,
So difference or change in volume is,
4 pie rh - 2 pie rh = 2pie rh (2 - 1)
2 pie rh (Ans)
