Yes, today is Pi Day! What is your favorite Pi math question?
An industrial tool for extreme measures of dimension.
I asked the Tootsie Pop owl what was the value of pi, but he always rounds it off the just 3.
You’re welcome. I hope it makes sense ...
Cannibal Pi
A man and his wife owned a flower shop. One day they went to Africa on a safari to look for exotic African violets. The safari was attacked by cannibals who captured the couple and took them to their village to be fried as people pie for dinner. Just as the cannibals began to prepare to pie crust, a herd of female sheep stampeded into the village. The cannibals immediately seized the female sheep and let the couple free. Only ewes can prevent florist fryers.
Groan....but thanks for posting it.
Logic, folks, logic!
Pi are round. Cornbread are square!
Unless it’s a peach cobbler for the church potluck.
Then pi are a deep-dish rectangle.
Ah....
But WHEN is “Pi Day”?
What month-day-hour-minute-second? (Pick a time zone, if you wish.)
If I have 1 pie, and you have 1 pie, how many pies do I have when you turn your back?
But the decimals in irrationals don’t repeat.

In the late nineteenth century there was a debate in professional math circles as to whether every number was the solution of an algebraic equation. The matter was resolved with a proof that pi is not such a number. Another transcendental number is e (~2.7182818284...), the base of natural logarithms and there is also the Euler-Mascheroni constant (~0.57712...). Any rational multiple of a transcendental number is also transcendental so there are a lot of them.
Those are repeating.
Oops! “Any rational multiple...” should be “Any non-zero rational multiple...”
The old The String Around The World puzzle.
Try it BEFORE you google.
I have had much fun with this one since high school.
Imagine I had a very long piece of string: long enough to wrap it around the equator of the Earth. And I’ll do just that. Yikes — that’s about 40,000 kilometers (or 25,000 miles) of string! I will make sure its pulled completely tight and connect both ends to each other: the result is that it lies flat onto the surface.
Now let me extend the string with just one measly meter. Compared to its total length that’s not a lot, is it? Once again I pull it tight, but now, with the added meter, it has come off the ground just a tiny bit. Assume that this extra distance (between the string and the Earth’s surface) is equally divided and thus the same all around the globe. How much would you guess this distance is? Surely this must be in the order of nanometers or whatnot, right?
What is the relationship of a pumpkin's diameter to its circumference?
Pumpkin Pi!
Ba-da-BING! I'll be here all week...
Prove that Pi is irrational.
If you serve pie with ice cream, how may scoops of ice cream does our President get?
Another fun one is crazy 9s.
Multiply any number by 9. The answer is always 9 or some number which can be eventually reduced to 9 by adding over and over.
Does this thing go on, like forever?
