The answer should be "close" to pie. It's very hard to explain and the maths are very hard. -=PI IS NOT GUARENTEED IN ANSWER=- *Post your answer in the comments*
Your answer won't be quit as accurate as it would be if you did it in a full scale. To do it in full scale all you need is a lot of matches (you need to know the EXACT number) a large piece of paper, and something to write with. First you take your first two matches and place them end to end and drawing lines at the end of each. After you finish drawing all of your lines you dump your matches on the piece of paper and spread them around. Then you count how many are crossing the lines. Then you get a calculator and do your number of matches divided by how many touched crossed the line. Your answer should be close to 3.141 3.14% Pi
