    the ratio of the big area to the small area is \(425:68\) which reduces to \(25:4\) or \(\frac{25}{4}\) the ratio of the sides is therefore the square root of that, namely \( \frac{5}{2}\)

    ok in any case that makes the midpoint \((-8,-3)\) so the equation is \[(x+8)^2+(y+3)^2=r^2\]now we need \(r\)

    the distance between \((-8,-3)\) and \((-5,-3)\) is evidently 3 (from -8 to -5 is 3 units) so \(r=3\)
