John,
I did, of course, mean to type "your problem is not stated clearly enough". Robert replied by explaining that he is trying to determine the diamter of a hole by inserting three cylinders in the hole one of which can be enlarged until it fits tightly. So it sounds to me like four mutually tangent circles ... the three smaller circles mutually externally tangent and each internally tangent to the hole . . . the "circumscribing circle.
