Question

Standard equation & general equation of a circle are same or different?

Answer 1

Dear Student,

The standard equation of circle with centre (h,k) with radius r is given by (x – h)² + (y – k)² = r².
The general equation of circle is given by x² + y² + 2gx +2fy + c = 0. The centre of the circle is (-g, -f) and the radius is √(g² + f² - c).
Both the equation can be converted into one another form so we can say that both are same.
