EZNEC gives the junctions of the segments on the circle. For four segments/turn, the length of each segnent is the radius times SQRT(2). As the number of segments increases, the circle is more closely approximated, but the area of the polygon formed by the segments is always smaller than the area of the circle.
I would prefer it if the area of the polygon formed by the segments were made the same as for the circle, but EZNEC does not make that correction.
