The equation of a circle comes in two forms. Simplify the right side. The standard equation of a circle with the center at and radius is Parametric Equations of a Circle The parametric equations of a circle with the center at and radius are General Equation of a Circle.
The general equation of any type of circle is represented by.
However the condition for the equation to represent a circle is. Find the centre and radius of the circle with the given equation of a circle. Also it can find equation of a circle given its center and radius. The standard equation for a circle centered at the point h k with radius r is.
