Hi all, I want to draw some proper VENN diagrams in which case I have the radii and areas of two circles, and I know the area of overlap. I had a look at http://mathworld.wolfram.com/Circle-CircleIntersection.html - it solves the area of two overlapping circles dependend on the distance of the two circles from each other. I can't figure out how to solve the equation for d. Anyone here knows what the solution would be? Thanks Markus
