Question 200519
the center of the circle is the midpoint of the diameter


(-6+2)/2 = -2


(3+5)/2 = 4  ___  so the center is (-2,4)


the radius is half the length of the diameter


sqrt[(2+6)^2 + (5-3)^2] = sqrt(68) = 2 sqrt(17)
so radius is sqrt(17)


using the general equation for a circle ___ (x+2)^2 + (y-4)^2 = 17
