md2,

You were asked to write posts that we can understand. Your complete failure to engage in any two-way conversation here is becoming an issue. If you wish to stay on our forum much longer, we demand that you start writing posts we understand, and that you sometimes respond to what people write to you (even when their posts have just been requests for clarification thus far).

diagonal of square inscribed oval is

 

[latex]8 * \sqrt{\left(\frac{a^2b^2}{a^2+b^2}\right)}[/latex]

 

where 2a and 2b are the major and minor axes

 

I hope...
