Step 1: Note down the given  circle equation

            EXAMPLE: (x -2)^2 + (y + 1)^2 = \frac{169}{4}

Step 2: Compare the given equation with the Standard Form of circle equation.

          EXAMPLE: [math](x-2)^2+\left[y-\left(-1\right)\right]^2=\frac{169}{4}[/math] Compare it with

           (x - h)^2 + (y - k)^2 = r^2

          Where center  (h, k) and radius r  

Step 3: Identify the r, h and k values.

            NOTE: r- radius

                        h is x-coordinate

                        k is y- coordinate of the center.

          EXAMPLE; (h, k) = (2, -1), r = \frac{168}{4}
