The circumference of the base of a right circular cylinder is 220 cm. If the height of the cylinder is 2 m find the lateral surface area of the cylinder.

Answer :

Let the height & radius of the cylinder be h & r cm respectively.

Given height is 2m = 200cm


As, circumference of base = 220


2πr = 220



r = 35 cm


As, Lateral surface of cylinder = 2πrh




= 44000 cm2
