Question

The center of a circle is at (–4, 2) and its radius is 9.

What is the equation of the circle?


(x−4)2+(y+2)2=3
(x+4)2+(y−2)2=3
(x−4)2+(y+2)2=9
(x+4)2+(y−2)2=9
(x−4)2+(y+2)2=81
(x+4)2+(y−2)2=81

Answer 1

Answer: fourth choice

Step-by-step explanation:

Answer 2

Answer:

formula for circle is

(x-h)^2+(y-k)^2=r^2

so the answer is sixth
