Circle S has an equation of (x + 16)2 + (y – 9)2 = 4. What is the center and radius of circle S? Answer Center: (16, -9); Radius: 4 Center: (-16, 9); Radius: 4 Center: (16, -9); Radius: 2 Center: (-16, 9); Radius: 2
center-radius form for the equation of a circle... (x-h)^2 + (y - k)^2 = r^2 where (h, k) is your center and r is your radius.
