6.3.2 Review of the Equation of a Circle

• center: (6, -4)

  radius = 49

• center: (6, -4)

  radius = 7

• center: (-6, 4)

  radius = 7

• center: (-6, 4)

  radius = 49

• center: (5, 0)

  radius = 4

• center: (0, 5)

  radius = 2

• center: (5, 0)

  radius = 2

• center: (0, 0)

  radius = 2

• None of these equations represent the circle.
