Couldn't you use Javascript calls to generate the square root, then pass
them on to the Flash movie as variables?

++ If memory serves, I think a circle is defined by x**2 + y**2 = r**2
++ (where **2 means squared), so for a given x, y would be square root(

++ (0,0), as you seem to be). Now to get the square root
