a road roller takes 750 complete revolutions to move once over to level a road . Find the area of the road if the diameter of the road roller is 84 cm and length is 1 m

Answer»

Step-by-step explanation:

DIAMETER of road roller=84cm

radius=84/2=42cm=0.42m

length=1m

csa of cylinder=2*22/7*0.42*1

26.4m²

area covered by road roller in 1 revolution=26.4m²

area covered by road roller in 750 revolution=26.4*750=19,800m²
