**Reiny**, Thursday, December 8, 2011 at 11:49amcomplete the square

x2 - 6x + ..... + y^2 + 12y + .... = -33

x^2 - 6x + 9 + y^2 + 12y + 36 = -33 + 9 + 36

(x+3)^2 + (y+6)^2 = 12

I am sure you can finish the question from here,

but...

I am puzzles by 3. and 4.

it says to label centres and in 4. to mark the radius of each.

That suggests that there are more than one circle.
