find center and radius of circle
(x6)^2+(y+9)^2=121
(x6)^2 (x6)^2
(y+9)^2=121121(x6)^2
(y+9)^2=+/ ã121(x6)^2
9 9
y=9+/ã121(x6)^2
does anyone know is this the answer or do I go further???????????????????????

Your equation is already in the standard form of
(xh)^2 + (yk)^2 = r^2
where (h,k) is the centre and the radius is r
so for (x6)^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
9 9
in a sequential solution.
What is that supposed to mean?
Are you all from the same class?
