# How Many Revolution Will The Wheel?

The radius of a circular wheel is 1.75 metres. How many revolutions will the wheel make to travel 44 km ?

- 5000
- 6000
- 3000
- 4000

**Answer: (4) 4000**

**Explanation:-**

The radius of a circular wheel = 1.75 m

**Formula-**

**The circumference of a circular wheel = 2 x pai x r**

**Where, r = radius of the circle**

Then, the distance covered by a circular in a round = 2 x 22 x 1.75/7

= 44 x . 25

= 11 meters

Total distance covered by circular wheel = 44 km

= 44 x 1000 m (1 km = 1000 m)

= 44000 m

The number of revolutions made by circular wheel = 44000/11

= 4000

Hence, the answer is (4) 4000.
