Question

the diameter of a wheel is 1.4 metre how many revolution will it make to cover a distance of 2 kilometre 200 m​

Answer 1

Step-by-step explanation:

The distance that a wheel travels in one rotation is simply the circumference of the circle.

Circumference of wheel= 2* pi* radius.

2* (22/7)*14= 88 cm

So wheel can travel 88 cm in 1 rotation.

And it has to cover 2200m(220000cm)

So 220000/88=2500

So wheel rotates 2500 times to travel 2km 200m
