Given the circle touches the lines \(|x-2| + |y-3| = 4\), which represent boundary lines of a square or diamond shaped region.
The circle must be tangent to these lines, so its radius equals the distance from center to each line.
Center of circle \((h,k)\) can be assumed, and from tangency conditions the circle equation is found to be
\[
x^2 + y^2 - 4x - 6y + 5 = 0.
\]
