# Find the Radius of the Wheel, If

A wheel makes 4000 revolutions in moving a distance of 44 kms. Find the radius of the wheel

- 69 metres
- 57 metres
- 77 metres
- 175 metres

**Answer: (4) 1.75 metres
Explanation:-
**Distance covered by wheel in 4000 revolutions = 44km

44km = 44 x 1000

= 44000 metres

circumference of wheel = distance covered in one round by wheel

= 44000/4000

thus, circumference of wheel = 11 metres = 2pr

r = 11/2p

r = 11 x 7 /2 x 22

r = 1.75 metres

Hence, the radius of wheel is 1.75 metres.
