# How to contact you or the only 1 answer friend which you vote for as 100% may be it right?

But it is not the best the I have it and not using PI ; still if you reverse the question u will get Pi ;

I said It is new formula and the right angle triangle roll is particular case of it even the circle is also particular case ; so my formula is general and approved practicaly ; I am sorry to my freind who give the only answer assuming that the formula is easy and for accurate answer there is other formula; sorry my formula is even simpler than your answer.

Here is an invite for universities and prof. to discuss it .

thanks for all.
