Explanation:

Total distance covered in 200 rotation = 440 m

Distance covered in 1 rotation

= 440 / 200

= 2.2 m

Distance covered in 1 rotation = Circumference of circle so

circumference = 2πr

2.2 = 2 * 22/7 * r

2.2 = 6.28 r

r = 2.2 / 6.28

r = 0.35 m

Now Area of the wheel

= πr²

= 22 /7 * 0.35 * 0.35

= 0.385 m²

Hope it will help :)❤
