A road roller takes 750 complete revolutions to move class

Radius of the roller = 42 100 m. Also, given that the roller takes 750 complete revolutions to level the whole road. Therefore, the area of road = 750 (Area covered in one revolution) The area of road = 750 (Lateral surface area of cylinder) The area of road = 750 × 2 π r h. The area of road = 750 × 2 × 22 7 × 42 100 × 1 = 750 × 2 × 22

A Road Roller Takes 750 Complete Revolutions to Move

2  · In one revolution, the roller will cover an area equal to its lateral surface area. Thus, in 1 revolution, area of the road covered = 2πrh = 2 x `22/7` x 42 cm x 1m = 2 x `22/7` x `42/100` m x 1 m = `264/400 m^2` In 750 revolutions, area of the road covered = `(750 xx 264/100) m^2`
