What is the center and radius of the circle with equation #36x^2 - 36x + 36y^2 - 24y = 131#?
The General equation of circle is :
Dividing all terms by 36 ( To remove the coefficient of x^2 and y^2)
Comparing the given equation with the general equation of circle we get,
or g =
or f =
Center of the circle (h,k) = (
