2 items are filed under this topic.    Page1/1            Two overlapping circles 2013-05-22 From Alexandra:There are two overlapping circles. The two non-overlapping regions have areas A and B. As the area of overlap changes, the values of A and B also change. Prove that no matter how big and small the overlap is, the difference between A and B is always the same.Answered by Penny Nom.     Two overlapping circles 2010-04-12 From Scott:There are two circles, big circle with radius R and small one with radius r. They intersect and overlap in such a way that the common area formed is 1/2 pi r^2 (half the area of the small circle). The Question is: suppose we have known the radius r of the small circle, and the distance between the two circle centers, what should the radius R of the large circle be?Answered by Chris Fisher.
