The diameter of a garden roller is 1.4 metre and it is 2 metre long. The area covered by the roller in 5 revolutions is :
We know that, Surface area of cylinder = π × d × L Where, d and L are diameter and length of the cylinder
Given, Diameter of the roller = 1.4 m & Length of the roller = 2 m
∴ Surface area of the roller = π × 1.4 × 2 = (22/7) × 1.4 × 2 = 8.8 m2
∴ Area covered by 5 revolution = 5 × 8.8 m2 = 44 m2
