The curved surface area of a cylinder is `1320 c m^2` and its base had diameter 21cm. Find the height and the volume of the cylinder.

Explanation

given radius `=21/2cm`
given that curved surface area `=1320cm^2`
or,`2pirh=1320`
`2pixx(21/2)xxh=1320`

so `h=20cm`
so volume`=pir^2h`
`=pixx(21/2)^2xx20`
`=2310cm^3`
