Both lists should be embedde in one, so that the unique command Centroid[Polygon] will converge, by increasing the sides n, into the value computed with circle. In other words, with few sides the computed point is far from the one coming from exact calculations. Thanks&Regards Philippe]]>

Point A (centroid) with few sides is quite discrepant to more accurate one (n=19). The main difficulty for me resides on defining (via slider) the path of the voided figure regarding the second circle. Regards Philippe]]>

It could be an ... assist for theoretical demonstations. Regards and compliments, Noel. Philippe PS: by activating the animation, see the position of centroid G, always there! https://ggbm.at/562217]]>
