The curved surface area of a cylindrical pillar is `264\ m^2` and its volume is `924\ m^3` . Find the diameter and the height of the pillar.

Text Solution

Verified by Experts

C.S.A of the cylinder = `2pirh`
`264=2xx22/7xxrh`
`rh=1848/44`
`rh=42`_______1
Volume of cylinder, `V = pir^2h`
`924=22/7xxr(rh)`
`r=294/42`
`r=7m`
