Question

How to calculate distance covered by a wheel of radius 1.4m,if it makes 250 revolution?

Answer 1

radius=1.4m

circumference of wheel=2r x pi = (2 x 1.4 x 22)/7 = 8.8m

therefore distance covered by wheel in one revolution is 8.8m

distance covered by wheel in 250 revolutions=2200m=2.2km

Answer 2

hey mate here is the answer

One revolution is

2πr = 2π×1.4m = 2.8π m

So 250 is approximately

250/ 2.8π ≈ 250/8.8 = 28.44revolutions.
