Circle Revolutions and the Coin Rotation Paradox

The concept of a circle‘s revolution involves understanding its circumference, which is the distance around the circle. To calculate the circumference of a circle with radius $r$, use the formula:

Circumference = $2\pi r$

Here, π is a constant approximately equal to $3,14159....$

Calculating the Number of Circle Revolutions to Cover a Distance

To determine the number of revolutions a circle with radius $$ makes to cover a certain distance $s$, divide the total distance by the circumference of the circle. The formula is:

Number of Revolutions = ${\displaystyle \frac{s}{2\pi r}}$.
