Your equation is already in the standard form of
(x-h)^2 + (y-k)^2 = r^2
where (h,k) is the centre and the radius is r
so for (x-6)^2+(y+9)^2=121
the centre is (6,-9) and the radius is 11
I have no clue what you were trying to do in your solution
Also this is the third student who has statements like your
in a sequential solution.
What is that supposed to mean?
Are you all from the same class?
