I have the radius and center $(x,y)$ on both circles, but how do I get the $(x,y)$ of the red circle, or in other words how do I get the $(x,y)$ position of where the circles intersect at the top or bottom?
How do I get get x and y position of a particular location on two intersecting circles (Vesica Pisces)?

0You can form a right triangle with the hypotenuse as the line between the center of one circle and the red dot (the length is the radius of the circles). The base of the triangle is half the distance between the centers of the two circles. You can then solve for the third side. – 2012-08-31
