Given an equilateral triangle of side 185 mm, how do I calculate the
diameter or radius of the circle that intersects with the three corners

My Zeus tables explain how to set up a drilling rig for a given
diameter, but not the reverse.

The formula would be helpful.

A link to a web site of such useful information would be wonderful!

More thought and less haste is an obvious answer (with apologies).
