1) Using only a straightedge and compass, constructed a circle, and multiple squares. After completing my diagram, i then measured my largest square... and could accurately predict the diameter of the circle. I've posted a video of this on Youtube.com for feedback but haven't received anything worthwhile.

2) (not related to the above mentioned drawing) Based off the measured drawing of a right triangle (10cm by 10cm with the hypotenuse at 14.14cm) I can predict the circumference of the circle out to 30 decimal places without using Pi. It is in the relationship between the chord and the arc. My question to CTK... is this "old news", or a by-product of the Sin/Co-Sin relationship?

My two videos are at www.youtube.com/user/shawnpatrick1968
I know this may be an unorthodox way of asking a question... but I don't know any other way...if that makes any sense.

So, to sum up my post here at CTK, "Hey anyone with a good math background, check out my two videos, 'squaring the circle' and 'world without Pi' and leave feedback, good or bad.

Thank you! Shawn
