The area of the (inside) of a circle - the circle itself is a line with no area - is calculated by:
pi * r2
the perimeter - also called the circumference is the length around the circle and is calculated:
2 * pi * r
where "r" is the radius, the distance from the center to the edge of the circle and "pi" is the irrational number 3.14159....
