A solid cylinder has a total surface area of `231\ c m^2dot` Its curved surface area is `2/3` of the total surface area. Find the volume of the cylinder.

Explanation

T.S.A of cylinder = `231cm^2`

A.T.Q

`C.S.A = 2/3 T.S.A`

`C.S.A = 2/3xx231`=`154cm^2`

Now, `C.S.A = 2pirh`

`2pirh=154`___1

As we know that `2pirh+2pir^2=231`

`154+2xx22/7xxr^2=231` (from1)
