How to find Equation of a Circle

the equation of a circle provides an algebraic way to describe a circle and in this article, we teach you how to write two forms of the Equation of a Circle. Rules for Equation of a Circle Equation of circles in standard form: \((x- h)^2+( y-k)^2= r^2\) Center: (h,k), Radius: r Equation of circles in general form: \(x^2+y^2+Ax+By+C=0\) Examples Equation of a Circle - Example 1: Write the standard form equation of each circle.\(x^2+ y^2-4x-6y+9=0\) Solution: The standard form of circle equation is: \((x- h)^2+( y-k)^2= r^2 \)where the radius of the circle is \(r\), and...
