I don't know if this way may be of any help:
Let the x-value of the centre of the circle and
let the y-value of the centre of the circle and
let the coordinates of a point on the circle
Than the equation describes the circle completely.
Put in the values you know. You'll get 2 equations which you can solve for and .
Don't be afraid: The 2 equations look very ugly at the beginning but all squares will vanish rapidly.
