Wild About Math!

Now that the MMM #20 submission deadline is past …

In the next few days, Quan and Daniel will be picking a random winner for MMM #20 over at Blinkdagger. We received 20 solutions. What’s very interesting to me is that, of those 20, two people were able to solve the problem without using trigonometry. Here’s a hint, can you tell if the center piece of the pie is bigger than either of the edge pieces without computing the exact area of any of the pieces? It’s too late to submit an entry if you haven’t already, so my question is just for fun. Leave a comment on this post if you see an easy way to solve the problem.

If you’re interesting in following my tweets, not all will be about Math, my twitter name is slederman.

If you twitter a fair amount about Math leave your twitter name in the comments and I’ll follow you.

MMM #19: Two winners!

We had 25 submissions for MMM #19 so I decided to give out two prizes! Random.org picked the numbers 6 and 22, which corresponded to the entries from Patrick Swickard and Todd Trimble. Congratulations to the two of you! I’ll be contacting you to get you your prizes!

Everyone who submitted an entry got the right answer, which I would expect since a quick calculator check would verify the answer. Some people explained their answers better than others. The most-straightforward solution I saw was this one by Ron Frederick.
