    \[(x-5)^2+(y+3)^2=25\] looks like \[(x-h)^2+(y-k)^2=r^2\] you have to identify \(h, k, r\)

    this is an overlooked but important skill, recoginizing the specific from the general in this case \(h=5,k=-3\) and since \(r^2=25\) you know \(r=5\)

    that means your circle has center \((5,-3)\) and radius \(5\)

    since \((5,-3)\) is the center of the circle, it is certainly in the interior of the circle
