Find the Polar Circumference of a Circle
1. Draw a line from the center to the edge of the circle.
2. Drop a perpendicular from the end of the line to the edge of the circle.
3. Measure the distance between the two points where the lines intersect.
4. Divide that number by 2 and multiply it by Pi (π).
5. Subtract the result from the radius of the circle.
