    radius is 8; center is at (13, 0).

    Step-by-step explanation:

    Compare the given (x - 13) ^ 2 + y ^ 2 = 64 to:

    (x - h) ^2 + (y - k) ^2 = r^2. (h, k) represents the center

    and r the radius.

    Since 64 = r^2, r = the radius = 8 units = r

    We also see that h = 13 and k = 0.

    Thus, the center of the given circle is (13, 0).
