Area of Intersection between Two Circles

Question

Given two circles:

• C1 at (x1, y1) with radius1
• C2 at (x2, y2) with radius2

Answer 1

You might want to check out this analytical solution and apply the formula with your input values.

Another Formula is given here for when the radii are equal:

Area = r^2*(q - sin(q))  where q = 2*acos(c/2r),
where c = distance between centers and r is the common radius.
