The diameter of the wheel of a car is \( 35 \mathrm{~cm} \). How much distance will it cover in 1000 revolutions?

Given:

The diameter of the wheel of a car is \( 35 \mathrm{~cm} \). 

To do:

We have to find the distance covered by the car in 1000 revolutions.
Solution:
 The radius of the wheel of the car $r=\frac{35}{2}\ cm$.

The distance covered by the car in 1 revolution is equal to the circumference of the wheel of the car.

Therefore,

The distance covered by the car in 1000 revolutions $=1000\times2\pi r$

$=1000\times2\times\frac{22}{7}\times\frac{35}{2}\ cm$

$=110000\ cm$

$=\frac{110000}{100}\ m$

$=1100\ m$

The distance covered by the car in 1000 revolutions is 1100 m.
