It's national Pi Day, as in 3.14, because it's March 14th. But a recent poll found a third of Americans don't know what "pi" is. Some just have a vague notion it has something to do with math.
19% said they had no idea what pi is, 3% thought it was the hypotenuse of a triangle, 2% said angles in a parallelogram, 1% said the volume of water, and 7% thought it was the "mass of a pie," spelled P-I-E. (???)
Two-thirds knew the correct answer: It's the ratio of a circle's circumference to its diameter. It's used it all areas of math and physics to calculate stuff.
But here's what you really care about: As always, a bunch of places have deals on PIZZA and ACTUAL pies today. Here are a few you might want to check out:
