Question

Find the distance covered by the wheel of a bus in 2000 rotation if the diameter of the wheel is 98 cm

Answer 1

Given
Dia of wheel =98cm
Radius =49cm

Circumference of wheel(distance covered in 1 rotation) =
$2\pi \: r$
=2x22/7 x49=308cm

In 2000 rotation distance covered =2000x308
=616000cm

=6160m
=6.16km
