What is its center? What is the standard equation of the circle describing the plate's boundary?
----------------------
Find the perpendicular bisectors of AB and AC (or BC).
The intersection of them is the center of the circle (h,k).
================
The distance from the center to A, B or C is the radius r.
 is the equation of the circle.
