The equation is x^2 + (y+5) ^2=81. find the center and radius

The center is (0,-5) and the radius is 9

Step-by-step explanation:

The equation of a circle can be given by

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

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

(x-0) ^2 + (y - - 5) ^2 = 9^2

The center is (0,-5) and the radius is 9
