The standard form of a circle is:

        ...(i)

Where, (h,k) is center and r is the radius.

We have,

          ...(ii)

On comparing (i) and (ii), we get

So, the center of the circle is (3,0) and the radius of the circle is .

Now, the circumference of the circle is:

Therefore, the circumference of the circle is about 35.5 units.
