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

The circumference of a circle is equivalent to the distance covered in one revolution of the wheel.

## Answer: The distance covered by the wheel is 1980 cm.

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

**Explanation:**

Given: Diameter of the wheel = 1.26 cm

Number of revolutions = 500

Distance traveled = Circumference of circle × Number of revolutions

The 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
