Given a circle of radius r, whose center is distance R from point P and which always lies in a plane perpendicular to line defined by P and center of circle (r) at distance R. All points of the circle will always lie within the surface of a sphere centered on P of radius= sqr( r^2 +R^2). I'm pretty confident on my result but intuitively I didn't expect this.
