We can clearly see the graph of a circle with the equation (x-a)^2+(y-b)^2=r^2 in red color. If we change the values of a, b and r using their corresponding slide bars we will see that the position and size of the circle gets changed. Let us observe how the size and position of the circle changes as we change the values of a, b and r
