The equation of a circle is (x+4)2+(y−5)2=121.
What is the center and radius of the circle?

(a) center: (−4, 5); radius: 11
(b) center: (4, −5); radius: 11
(c) center: (−4, 5); radius: 121
(d) center: (−4, −5); radius: 121

The center is and the radius is .

Step-by-step explanation:

The center-radius form for a circle is:

where is the center and is the radius.

The center is and the radius is .

(a) center: (−4, 5); radius: 11

Step-by-step explanation:

(x+4)² + (y−5)² = 121

(x-h)² + (y-k)² = r²

r² = 121

r =11
