#### Solution

The disstance covered by the wheel in one revolution is equal to the circumference of the wheel.

$\text{ Circumference }= \pi r^2$
$= \frac{22}{7} \left( \frac{35}{2} \right)^2$
$= \frac{22}{7} \left( \frac{35}{2} \right)^2$
$= 962 . 5 cm$
The distance covered by the wheel in one revolution (in m) is given by
$\frac{962 . 5}{100} = 9 . 625 m$
