Question

The lateral surface area of a cylinder of length 14m is 220 m². Find the volume of the cylinder.

Answer 1

Given that length is 14m and lateral surface area is 220 m²

Lateral surface area of cylinder= 2πrh

220= 2 × 22/7 × r × 14

r = 2.5m

Therefore volume of the cylinder = πr²h

V= 22/7 × 2.5× 2.5 × 14

V = 55 × 5 = 275 cm³
