Ответ:
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.
