    x2+y2-4x+16y-13

    Step-by-step explanation:

    center (h, k) = 2,-8

    radius (r) = 9

    we know

    (x-h) 2 + (y-k) 2=r2

    now insert above given information

    (x-2) 2 + (y+8) 2=9*9

    9^2 = (x+2) ^2 + (y+8) ^2

    Step-by-step explanation:

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