+273 How many inches are in the circumference of a great circle of a sphere which has surface area of \(196\pi \) sq in? Express your answer in terms of \(\pi\).
+2668 The formula for the radius of the sphere is \(4 \pi r^2\). We know that this is equal to \(196 \pi\). Setting these equal and solving for r, we find that \(r = 7\), meaning the circumference is \(2 \pi r = \color{brown}\boxed{14 \pi}\)
