Area of Intersecting Circles
Calculate area of intersecting circles
The area of intersecting circles can be calculated as
Thanks to Eric Eberly for providing this information.
If radii r1, r2 and distance d between the centers are given - then the angles α1 and α2 can be calculated as
α1 = acos[(d2 + r12 - r22)/(2 d r1)]
α2 = acos[(d2 + r22 - r12)/(2 d r2)]
