उत्तर

The number of revolutions made by a circle of radius r to cover a distance s is `underlinebb(s/(2πr))`.

Explanation:

Given: A circle (wheel) of radius r rolls a distance s.

Step wise calculation:

1. Distance in one revolution = circumference = 2πr.

2. Number of revolutions = Total distance ÷ Distance per revolution

= s ÷ (2πr)

= `s/(2πr)`

The number of revolutions = `s/(2πr)`.
