Question

a bicycle wheel turns 15times in covering a distance of 66m.Find the radius of the wheel

Answer 1

Answer:

25 times.you can try it this following way.

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 22 metres (2200 cm)

So 2200/88=25

So wheel rotates 25 times to travel 22 meters.
