    (x + 9.3) ^2 + (y - 4.1) ^2 = 13

    Step-by-step explanation:

    The standard form equation of a circle centered at (h, k) with radius r is ...

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

    Putting your numbers into this form gives ...

    (x - (-9.3)) ^2 + (y - 4.1) ^2 = (√13) ^2

    (x + 9.3) ^2 + (y - 4.1) ^2 = 13
