I wrote 8 as an answer for Question #1 and got it marked wrong?  When he unfolds the paper, how many different-sized central angles (less than 360º) are formed? 
I guess what's confusing me is is it really 8 different sized central angles that are less than 360* or is less or is it more?   Please help,I have until Friday to get the correct answer.  Thanks.
