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

Given:


The diameter of the Wheel = 98 cm



Radius = 49 cm = 0.49 m



Circumference of circle = 2πr = distance in one rotation


Circumference of Circle = 2 × 3.14 × 0.49 = 3.078m


Distance in 2000 rotation = 2000 × 3.078 = 6156 m
