Answer:

The standard form of a circle is (x - c)² + (y - d)² = r² where (c, d) is the center and r is the radius. This means that the center is (0, -7) and the radius is 8.

Answer:  Center = (0, -7)

                Radius = 8

Step-by-step explanation:

The equation of a circle is: (x - h)² + (y - k)² = r²     where

  • (h, k) is the center
  • r is the radius

       x²   + (y + 7)² = 64

→   (x - 0)² + (y - (-7))² = 8²

           ↓              ↓       ↓

          h=0        k=-7     r=8

  • (h, k) = (0, -7)
  • r = 8
