The curved surface area of the cylinder is `1760cm^2.` and its volume is `12320cm^2` Find its height.

Explanation

curved surface of cylinder=`2 pi r h`

`2 pi r h = 760`

`2 xx 22/7 xx r xx h = 1760`

`rh = 280`

volume of cylinder=`pi r^2h= 12320`

`r^2h = 3920`

dividing both equations, we get

`(r^2h)/(rh) = 3920/280`
