a circle with center \((h,k)\) and radius \(r\) will have the formula: \[\Large \left( xh \right)^2+\left( yk \right)^2=r^2\]

so in your formula: what's the center supposed to be? and what's the radius is supposed to be?

center is (1,3)... yes but \(\large r \ne 4\) \[\Large \color{green}{r^2=4}\]
