Question

A car has a tyre of diameter 28 cm.What is the distance covered by the car if the tyre rotates 150 times?

• A. 124 m
• B. 132 m
• C. 136 m
• D. 142 m

Answer 1

The correct option is B 132 m

Circumference of tyre = 2 $\pi$ r = Distance travelled in each rotation
Given: Diameter = 28 cm, hence radius = 14 cm

Distance covered in 1 rotation = 2 $\pi$ 14 = 88 cm

Distance covered in 150 rotation = 88 $\times$ 150 = 13200 cm = 132 m
