Tricky math problem

Hi Guys,

I'm new to this forum and would like to put forward a math problem I am struggling to find a solution to, the question is:

You have a circle of which you know the radius of. The circle has a 2mm section through the diameter of the circle (which cannot be used). You need to fit 6 circles within the inner circumference of the larger circle of one side. What is the largest circles you can fit within this?

I have been trying to formulate an equation to work this out but keep coming against hurdles every time I come close. Any ideas??

Please see attachment for clearer explanation

Here's a solution to your problem. It may not be what you want since a numeric solution of an equation is required. (Wolfram alpha had a crack at an analytic solution, but didn't really arrive at such.)

Thanks from topsquark and Joppy
