A wheel makes 500 revolutions in covering a distance of 44 km. Find the radius of the wheel.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 14 m.
Distance = 44 km = 44000 m
Distance covered in one revolution = 44000/500 = 88 m
2πr = 88
⇒ 2 × (22/7) × r = 88
⇒ r = 14 m
