Intrinsic Geometry of Cyclic Heptagons/Octagons via "New" Brahmagupta Formula

We get a simple(st) system of equations for the area and area times circumradius of cyclic heptagons/octagons via new Brahmagupta formula.By Groebner basis techniques we get minimal equations (for any concrete instances we have tested), what is not the case with iterated resultants approach.
