If the wheel of a bus travels a distance of 44 m by rolling 20 times find the radius of wheel?

To find the radius of the wheel, we can use the formula:

Distance traveled by one revolution of the wheel = 2πr

Given that the wheel travels a distance of 44 m by rolling 20 times, we can calculate the distance traveled by one revolution of the wheel:

Distance traveled by one revolution = 44 m / 20 = 2.2 m

Now, we can set this distance equal to 2πr and solve for the radius (r):

2.2 = 2πr

r = 2.2 / (2π) ≈ 0.35 m

Therefore, the radius of the wheel is approximately 0.35 meters.

The distance travelled by the wheel in one revolution = Circumference of the wheel

Therefore, 20 x Circumference of the wheel = 44 m

=> Circumference of the wheel = 44/20 = 2.2 m

Now, Circumference of the wheel = 2πr

=> 2.2 = 2 x (22/7) x r

=> r = 2.2 x 7/44 = 0.35 m

Therefore, the radius of the wheel is 0.35 m.
