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.
