What is the center of the circle x2 + (y+7) 2=49?

The center is at (0,-7) and the radius is 7

Step-by-step explanation:

We can write the equation of a circle as

(x-h) ^2 + (y-k) ^2 = r^2 where (h, k) is the center and r is the radius

x^2 + (y+7) ^2=49

Rewriting

(x-0) ^2 + (y - - 7) ^2 = 7^2

The center is at (0,-7) and the radius is 7
