The ratio between the curved surface area and the total surface area of a right circular cylinder is 1 : 2. Find the volume of the cylinder, if its total surface area is 616 cm2.
Given,
= 
= 
and, total surface area of cylinder = 616 cm2
= 
So, 2πr(h+r) = 616
= 2πr(2r) = 616
= r2 = 
= r = 
Hence, volume of cylinder = πr2h =
