Question

a road roller takes 900 complete revolutions to move once over to level a road. find the area of the road level a road. find the atea og the road if the diameter of the roadroller is 126 cm and its length is 2.5 m.​

Answer 1

Given:-

length of road roller = 2.5m =

diameter = 126 cm = 1.26m

Radius = 0.61 m

CSA of road roller = 2πrh = 2 x 3.14 x 0.61 x 2.5m² = 9.577m²

Area of the road = 900 x 9.577m² = 8619.3m²
