Question

A wheel has a radius of 28 cm.how many revolutions will it make to travel 704 meter.

Answer 1

Explanation:

Number of revolutions made by wheel

`= (distance \: travelled)/(circumference \: of \: wheel) \\ \\ = (704)/(2\pi \: r) \\ \\ = (704)/(2 * (22)/(7) * 28) \\ \\ = (704)/(2 * 22 * 4) \\ \\ = (704)/(176) \\ \\ = 4 \\`

Hence the wheel will make 4 revolutions.
