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
of the triangle?
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!
You mean like typing
"diameter of a circle on an equilateral triangle"
into google ?
which yields various site such as this ...

Rocket science, eh ?
