The center of a circle is at (-10, 6) and it has a radius of 4. What is the equation of the circle?

(x - 10) 2 + (y + 6) 2 = 16

(x - 10) 2 + (y + 6) 2 = 2

(x + 10) 2 + (y - 6) 2 = 2

(x + 10) 2 + (y - 6) 2 = 16

(h, k) = (-10,6)

r=4

r^2=16

h=-10

h=6

(x+10) ^2 + (y-6) ^2=16

The correct answer is A.
