Question

The diameter of the wheel of a car is 0.70m. Find the distance covered by it in 500 revolutions. Answer is 1100m but when I tried to do it I got some other answer. Please give a step by step explanation.

Answer 1

Step by step solution :

Diameter = 0.70 m

Radius = 0.70/2 = 0.35

Circumference of circle= 2πr

= 2 × 22/7 × 0.35

= 2.2m

The distance covered in 500 revolutions = 2.2 × 500

= 1100m
