Find the center and radius of the circle whose graph is shown. Write the standard form of the equation of the circle.
A. r = 
; (h, k) = (-4, 4); (x - 4)2 + (y + 4)2 = 2
B. r = 
; (h, k) = (-4, 4); (x + 4)2 + (y - 4)2 = 2
C. r = 2; (h, k) = (-4, 4); (x - 4)2 + (y + 4)2 = 4
D. r = 2; (h, k) = (-4, 4); (x + 4)2 + (y - 4)2 = 4
