64*pi=200.96 so B is the correct answer

No, it's a semicircle. A semicircle is half of a circle. So, the circumference will also be half of a full circumference.

ipwnbunnies · Answer

So, the diameter of the semicircle will actually be $$\frac{200.96 inches^2}{2}$$

ah right so you'd take 200.96/2 = 100.48
