A wheel makes 500 revolutions in covering a distance of 44 km. Find the radius of the wheel.

14 m

Number of revolutions made by the wheel = 500

Distance covered by the wheel = 44 km

The distance covered by the wheel in one revolution = 2πr meters.

The distance covered by the wheel in 500 revolutions = 500 × 2πr meters.

We know that the distance covered by the wheel is 44 km = 44,000 meters.

500 × 2πr = 44,000

1000πr = 44,000

r = 14 m
