Given the centers of the circles(say points a,b,c,d,e) and a fixed radius 'r'. The circles may be overlap each other. How to find the area of a given circle that is not overlapping with any other circles.

if there are only two circles we can easily find out the common area and subtract it from the circles area. But as there are more than two circles we cant directly subtract the common areas by considering two points at a time...

help me plzz....
