I am looking at the typical sphere-sphere intersection :
http://mathworld.wolfram.com/Sphere-SphereIntersection.html
And I was wondering how to reverse the equation to get the radius of the intersecting circle between two spheres.

Meaning that, given a radius for the intersection and two radii for the spheres, how to calculate the distance between them?

Edit: There is no need to reverse that equation.
Simpler formula (thank you, uncle Pythagoras)
distance = Sqrt(R^2-a^2) + Sqrt(r^2-a^2)
