Given: (3,-1) and (-11,7) are endpoints of a diameter of a cirle.
Find the radius, center coordinates, and equation in general form
------------------------------
Center Coordinates:
x coordinate: (3-11)/2 = -4
y coordinate: (-1+7)/2 = 3
Center: (-4,3)
--------------------------
Radius:
r = sqrt[(3--4)^2 + (-1-3)^2] = sqrt[49 + 16] = sqrt(65)
----------------------------
EQUATION:
(x+4)^2 + (y-3)^2 = 65
===========================
