Q29 of 94 Page 228

The diameter of a cylinder is 14 cm and its curved surface area is 220 cm2. the volume of the cylinder is

Given that,

Diameter = 14v cm


So, Radius = 7 cm


We know that,


Curved surface area of cylinder = 2rh


220 cm2 = 2rh


h =


h = 5 cm


Therefore,


Volume of cylinder = r2h


= × 7 × 7 × 5


= 770 cm3


Hence, option A is correct
