    The center is (5, - 2) and the radius is 9/2

    Step-by-step explanation:

    The equation of a circle can be written in the form

    (x-h) ^2 + (y-k) ^2 = r^2

    where (h, k) is the center and r is the radius

    (x - 5) ^2 + (y + 2) ^2 = 81/4

    (x - 5) ^2 + (y - - 2) ^2 = (9/2) ^2

    The center is (5, - 2) and the radius is 9/2
