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 = 2
rh
220 cm2 = 2
rh
h = 
h = 5 cm
Therefore,
Volume of cylinder = 
r2h
= 
× 7 × 7 × 5
= 770 cm3
Hence, option A is correct
