The Deep Dive
The equation of a circle is generally represented as \((x-h)^{2} + (y-k)^{2} = r^{2}\), where \((h, k)\) is the center and \(r\) is the radius. From the given equation \((x-8)^{2}+(y+13)^{2}=361\), we can see that the center is at \((8, -13)\) because those are the values of \(h\) and \(k\). The radius can be found by taking the square root of \(361\), which is \(19\). So, the center is \( (8, -13) \) and the radius is \( 19 \).
