Answer 1

A circle is centered at (5, −9) and has a radius of 12. Which of the following is the equation for this circle?

(x − 5)2 + (y + 9)2 = 12
(x − 5)2 + (y + 9)2 = 144
(x + 5)2 + (y − 9)2 = 144
(x + 5)2 + (y − 9)2 = 12

Answer 2

B

From google
The center-radius form of the circle equation is in the format (x – h)2 + (y – k)2 = r^2, with the center being at the point (h, k) and the radius being "r". This form of the equation is helpful, since you can easily find the center and the radius.
