The volume and the curved surface area of a cylinder are `1650 cm^3 and 660 c m^2` respectively. Find the radius and height of the cylinder.

Explanation

given curved surface area of cylinder`=2xxpixxrxxh=660`
or, `rxxh=105`

given volume of cylinder`=1650cm^3`
or, `pixxr^2**h=1650cm^3`
from above put value of `rxxh=105` in this equation we get
`pixxrxxhxxr=1650cm^3`
or,`pixx105xxr=1650cm^3`
or ,`r=5cm`
now put value of r in `rxxh=105`
we have `5xxh=105`
`h=21`
