The Circle touches both the *x* and *y* axes, this means that the radius of the circle touches both the *x* and *y* axes, this in turn means that the horizontal distance from the y-axis is equal to the vertical distance from the x-axis. Find the distance of between the center of the circle and the given point (2,1) and form a quadratic equation, then solve the quadratic equation.
