Given,
width = 63 cm
Diameter = 22cm
So, Radius(r) = 22/2 = 11 cm
Curved Surface Area of the roller =
2πrh
= 2 * 22/7 * 11 * 63
This is area covered in one revolution.
Therefore, the area covered in 200 revolutions is ---
4356 x 200 cm^2 = 8,71,200 cm^2
Hope this helps you.

A garden roller is 22cm in diameter and 63 cm in width. How much area will be covered in 200 revolution?
✏ Area it will cover in 200 revolutions = ❓
✏ Radius, r =
✏ r =
✏ r = 11 cm
= 2Πrh
= 2 × × 11 × 63
= 44 × 99
= 4356 cm sq.
= 4356 cm sq.
= 200 × 4356
= 871200 cm sq.
= 87.12 m sq.
