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:
How would I solve for d in the following equation?
A = 2r2arccos(d/2r) - 0.5sqrt(4r2d2 - d4)
or, with the values put in:
100 = 288arccos(d/24) - 0.5sqrt(576d2 - d4)
- The area of the overlap is 100
- The two circles have the same radius, 12
- d is unknown
