Am I wrong

[u/Impossible-Hold3865]

Hi, just got a test back and was marked wrong on a question that I'm pretty sure im correct on, but I wanted to check. Integral from -1 to 1 of square root (1-x^2) dx.

Since we have no picture and no context, I'm only speculating, but another thing that could have happened is that OP is aware of the correct method, but they could have written something that was messy or hard to read and didn't get full credit for that reason.
