Given:
The equation of a circle is:

To find:
Center and the circumference of the circle.
Solution:
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.
