When you write that the answer formats containing pi, you should make it so that is shows how you want the problem to be solved. I was asked to find the area of a circle with the diameter 10. Answer formats told me to write "25 pi", and I was frustrated, because it was the right answer, but the format was wrong. I tried some other combinations, and found out how the problem was to be solved. That being said, you should show clearer how you want the problem to be solved.
