    Answer:

    (x-1.3)^2 + (y+3.5)^2 = 37

    In general, (x-c)^2 + (y-k)^2 = r^2 where (c,k) is the center and r is the radius.

    So if the circle with radius 5 has center (3,-4) then it’s equation is:

    (x-3)^2 + (y+4)^2 = 25

    Notice that the second term is (y+4)^2 because the y-coordinate is -4 and y-(-4) = y+4
