Question

If a wheel of a bicycle covers 440m in 200 rotation. find the area of a wheel.​

Answer 1

Step-by-step 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 :)❤

Answer 2

Answer:

7/22

Step-by-step explanation:

Area = 400/200 × 400/200 ×1/4 × 7/22 = 7/22
