A question about the area of a circle (here's the circumference, work out the area) includes "an exact decimal" and "a multiple of pi" in the acceptable answer formats section. However, when I tried to answer with an exact decimal, I was told I was incorrect. When I clicked "show solution", only the "multiple of pi" answer was shown. This answer was accepted. Since the decimal answer I gave was correct, I believe there is an error in the acceptable answer formats list.
