E) 5
square forms two right angled triangles.   Any time we have a right angle triangle inside a circle, the hypotenuse is the diameter.   hypotenuse here = diagonal of the square = 8 sqrt(2) = diameter   =&gt; radius = 4 sqrt(2)   8√ 2πircumference of the circle = 2pi r = 8 pi sqrt(2)   Answer is 8√ 2π.
