False. because.....
the equation of a circle is (x-h)^2 + (y-k)^2 = r^2 and the center is (h,k)
if the center of a circle is (-5, -13) substitute the values into the equation
so....(x- -5)^2 + (y- -13)^2 = r^2 which is (x+5)^2 + (y+13)^2 = r^2
in this case, because you are only asking about the center of the circle from the equation the 81 or radius of the circle doesn't matter.
