What radius?
Some part or parts of your description are missing or wrong.

The equation for the GIVEN circle, after completing-the-squares is , so the radius for the given circle is .


If you want the a circle with center (3,7) and circumference 8pi, then
and you would find this "r" according to



and the equation then is . This IS NOT RELEVANT to your given equation.
