Okay, so I've found out about how circle-circle intersection works ( http://mathworld.wolfram.com/Circle-CircleIntersection.html ). I'm working with the following knowledge:(adsbygoogle = window.adsbygoogle || []).push({});

- The area of the overlap is 100
- The two circles have the same radius, 12
- d is unknown

How would I solve for d in the following equation?

A = 2r^{2}arccos(d/2r) - 0.5sqrt(4r^{2}d^{2}- d^{4})

or, with the values put in:

100 = 288arccos(d/24) - 0.5sqrt(576d^{2}- d^{4})
