I have question related to circle-packing. The problem is to find the circle of minimum radius enclosing four non-overlapping circles of arbitrary radius. I have to write a program in C for this question but have not been able to find a formula for the radius of the enclosing circle. Any help appreciated.

Question is just find the minimum radius of Circle circumscribing four circle of unequal radius. Please see this link for figure and some solution...But required a short approach/formula... –  Avinash Singh Mar 9 '12 at 17:03

Regarding your "test cases": how can even one circle of radius 2500 be contained in a circle of radius 1837? I looked at the link you posted. To make sense of your question I think the radius of the enclosed circles would have to be smaller. –  daniel Mar 9 '12 at 18:51
    
@daniel..Yes ur right..Test case are wrongly posted... –  Avinash Singh Mar 9 '12 at 18:54
