To find the center and radius from the equation \( 4(x-2)^{2}+4 y^{2}=4 \), we start by dividing the entire equation by 4 to simplify it: \[ (x-2)^{2} + y^{2} = 1 \] From this standard form of a circle's equation \((x-h)^{2} + (y-k)^{2} = r^{2}\), we can clearly see that the center \((h, k)\) is \((2, 0)\) and the radius \(r\) is \(\sqrt{1} = 1\). The center of the circle is (2, 0) and the radius is 1.
