Given:
The equation of a circle is
To find:
The center and radius of the given equation by completing the square.
Solution:
The standard form of a circle is
...(i)
where, (h,k) is center and r is radius of the circle.
We have,
It can be written as
...(ii)
On comparing (i) and (ii), we get
Therefore, the center is and the radius is units.
