# If π is Taken as 22 7 the Distance (In Metres) Covered by a Wheel of Diameter 35 Cm, in One Revolution, is - Mathematics

MCQ

If π is taken as $\frac{22}{7}$ the distance (in metres) covered by a wheel of diameter 35 cm, in one revolution, is

•  2.2

• 1.1

•  9.625

•  96.25

#### 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
$\frac{962 . 5}{100} = 9 . 625 m$
