A solid cylinder has a total surface area of 231 cm2. It curved surface area is of the total surface area. Find the volume of the cylinder.

Given,


Total surface area of cylinder = 231 cm2


Curved surface area =


so,


=


= 3 h = 2h + 2r


= h= 2r.............(i)


And,


=


=


=


=


= h = 2r = 2×3.5 = 7 cm


Volume of cylinder =
