Re: Overlapping circles

Hello W.H.,
The equation I get is: s = sqrt(d^2c^2)/2 + sqrt(4*d^2c^2)/2 + 3*d/2. I don't think it is easy to solve for d, so I didn't try. The square roots are intended to be the distance from the center of the chord to the center of each circle. My guess is that an equation in d^8 will result and I don't know whether that can be reduced.
