0 Posted 6 May 2014 · Report post If you mean unit area, the mean distance between two interior points of a unit regular n-gon converges to that of a disk. If you mean unit side, then the mean distance diverges, since that type of unit regular n-gon becomes the entire plane. 0 Share this post Link to post Share on other sites

0 Posted 7 May 2014 · Report post Empirically, by simulation. Or do some area integrals. For an equilateral triangle with unit sides it's 0.364791843300... For a square with unit side it's 0.521405433.... For a circle with unit radius it's 0.905414787... 0 Share this post Link to post Share on other sites
