The equation of a circle in general form is, x 2 + y 2 + Dx + Ey + F = 0, where D, E, and F are real numbers. To more easily identify the center and radius of a circle given in general form, we can …

Learn the equation of a circle in Maths, including standard and general forms, steps to find centre and radius, solved examples, and a calculator tool.

The equation of a circle is an algebraic equation that describes all the points at a fixed distance (the radius) from a central point (the center) on a coordinate plane.

If we "multiply out", the center-radius form, we obtain the "general form" of the equation of a circle. Notice that in this form, we can clearly see that the equation of a circle has both x2 and y2 terms and …
