A wheel makes 1000 revolutions in covering a distance of 88 km. the diameter of the wheel is?

Distance covered in one revolution = total distance travelled / total number of revolution.
= ( 88 x 1000) / 1000 m
= 88 m
We know that the distance covered in one revolution = circumference of the wheel.
⇒ πd = 88
⇒ 22d / 7 = 88
∴ d = 28 m
