# The Diameter of a Wheel is 1.26cm. What is The Distance Covered in 500 Revolution?

## Question: The diameter of a wheel is 1.26 cm. What is the distance covered in 500 revolution?

Circumference of circle is equivalent to distance covered in one revolution of the wheel.

## Answer: The distance covered by a wheel of diameter 1.26cm in 500 revolutions is 1980cm.

Let's find he distance covered by the wheel in 500 revolution.

## Explanation:

Given: Diameter of the wheel = 1.26cm

Number of revolutions = 500

Distance travelled = Circumference of circle x Number of revolutions

Circumference of a circle is the length of the complete boundary of a circle

Circumference of circle = 2πr

Distance covered in one revolution = (22/7) × 1.26 (since, diameter = 2r)

Hence, distance covered in 500 revolutions = 500 × (22/7) × 1.26 = 1980 cm

### Thus, distance covered by a wheel of diameter 1.26 cm in 500 revolutions is 1980 cm.
