    This is a problem of my own volition:

    given n concentric circles, each of which contain a point that can move on that circle, with radiu’s {r1, r2, …., rn}, find the geometric arrangement of these points to get a polygon of maximum area.

    The attached figure will help elucidate the setup:


    Okay, so we are given a few concentric circles, we don’t know how many. I’ll give a few ideas of mine. Let me assume that they aren’t equidistant.

    Plot the given figure in the Cartesian plane, with the common center as the origin (0,0).

    [ A co-ordinate geometric approach]

    Now we can fix a point on the first circle, then we can plot the other points variably, and then use the shoelace formula to find the co-ordinates as so to maximise the area.
