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.
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
