    the question is to build the figures so many sides to compare to circle around this figure, and the dependence of diameter of this figure to H ( like in picture ) will be going to 3,14

    Hey razera.

    I think you should take a look at how Archimedes solved this problem:

    Re: multi sides figure inside the circle

    compare the 3.14 to multiside figure inside the circle ( to its diagonal ) maybe we can get the side 'a' and find the 'H' without know the d ?
