Circular Inclusion
Sandefur, James; Mason, John
College Mathematics Journal, v44 n3 p193-201 May 2013
Given a family of "p" greater than or equal to 3 points in the plane, some three of them have the property that the smallest circle encompassing them
encompasses all "p" points. Similarly, we show that for "p" greater than or equal to 3 circles, there are three of them such that the smallest circle encompassing
them encompasses all the circles, and that there are three circles for which the smallest circle encompassing and tangent to them encompasses all the circles.
