Understanding Circle Circumference
The circumference of a circle is the distance around it. It's like the perimeter of a polygon, but for a circle. The circumference is always proportional to its diameter and radius.
Formula and Calculation
The formula to calculate the circumference (C) of a circle is given by:
$$C = 2 \pi r$$
Where:
- C is the Circumference of the circle
- π (Pi) is a mathematical constant, approximately equal to 3.14159
- r is the Radius of the circle
