Answer:

The center is (7,-4) and the radius is 3

Step-by-step explanation:

(x – 7)^2 + (y + 4)^2 = 9

The equation of a circle can be written as

(x – h)^2 + (y - k)^2 = r^2

where (h,k) is the center and r is the radius

Rewriting the original equation

(x – 7)^2 + (y -  - 4)^2 = 3^2

The center is (7,-4) and the radius is 3
