What are the coordinates for the center of the circle and the length of the radius ?

the answer to your question is D

 the correct option is

(D) (-7, -1), 6 units.

Step-by-step explanation:  We are given to find the co-ordinates of the center and the length of the radius of the following circle :

We know that

the STANDARD equation of a circle with center at the point (h, k) and radius of length r units is given by

From equation (i), we have

Comparing the above equation with the standard equation of a circle, we get

center, (h, k) = (-7, -1)  and radius, r = 6 units.

Thus, (D) is the correct option.
