Answer 2

The area of the ground pressed by it in 500 revolution is 2543.4 sq.m.

Step-by-step explanation:

Diameter of roller = 0.9 m

Radius of roller =$\frac{0.9}{2}=0.45 m$

Length of roller = 1.8 m

Curved surface area of roller = $2\pi r h = 2 \times 3.14 \times 0.45 \times 1.8 =5.0868 m^2$

Area covered in 1 revolution =$5.0868 m^2$

Area covered in 500 revolution =$5.0868 \times 500=2543.4m^2$

Hence the area of the ground pressed by it in 500 revolution is 2543.4 sq.m.
