Question

The radius of circle 35 mm find the distance covered by bus during the time which the whee
l make 500 revolution

Answer 1

Given
Radius ,r= 35mm
circumference of the wheel=
$2 \: \pi \: r$
=
$= 2 \times \frac{22}{7} \times 35 \\ = 2 \times 22 \times 5 \\ = 220 {mm}^{}$
the bus goes 220mm in one revaluation.
therefore
in 500 revaluation the goes =220×500mm
=110000mm
