Question

a road takes 750 compelete revolutions to move once over to level a road. find the area of the road, if the diameter of a road roller is 91 cm and length is 1.25 m

Answer 1

Hello friend

CSA of roller = 2πrh
CSA of roller= 2×22/7×91/2×125
CSA of roller = 207350cm^2
Area of road = CSA× revolution
Area of road = 207350× 750
Area of road = 155512500 cm^2
Area of road = 1555125 m^2
