What is Circumference of a circle?
The distance along the boundary of a circle is the Circumference of the circle. In other words, it is the total length of the boundary.
For example, if an athlete starts at a point on a circular track, then, the distance he covers around the track to reach the same point again is the circumference of the track.

How is circumference calculated?
To calculate the circumference, the radius of the circle is required.
For a circle with radius equal to ‘r’ units, the circumference is given by the formula:
Circumference = ???
The symbol \pi is used to represent Pi.
