The General equation of circle is :
Explanation:
So,
Dividing all terms by 36 ( To remove the coefficient of x^2 and y^2)
We get,
Now
Comparing the given equation with the general equation of circle we get,
2g =
or g =
Again,
2f =
or f =
And,
c=
Thus,
Center of the circle (h,k) = (
= (
And
Radius =
