    dependence between diameter and square based on the same diagonal

    dependence between diameter and square based on the same diagonal

    ( 4 * d / pierw(2) ) / ( Pi * d ) = 4 / ( pierw(2) * Pi ) = 0.9

    Re: dependence between diameter and square based on the same diagonal

    I think what the OP is saying is that the ratio of the perimeter of a square of diagonal length D to the circumference of a circle with diameter D is:

     \frac {P_{square}}{P_{circle}} = \frac {4 \frac D {\sqrt 2}}{\pi D} = \frac 4 {\pi \sqrt 2} = 0.9003..

    His notation "pierw(2)" apparently means "square root of 2." As to why he posted this - I have no idea.
