Flag Day Math

Tuesday, June 14. Flag Day. It’s nearly impossible for mathy folks to not tell this joke today.

Several engineers were attempting to measure the height of a flag pole. They only had a measuring tape, and they were getting quite frustrated trying to slide the tape up the pole. They could get the tape no more than a third of the way up the pole before it would bend and fall down.

A mathematician asks what they’re doing, and they explain. The mathematician offers to help. She removes the pole from the ground, sets it down, and measures it easily. She then returns the measuring tape to the engineers, and walks off.

When she leaves, one engineer says to the others, “That’s just like a mathematician! We need to know the height, and she gives us the length!”

Those who know it will also tell this one, or a variant.

How do statisticians determine which banner to hoist?
They take a flag poll.

And then there are jokes about specific flags.

I’m about as motivated as the guy who designed the Japanese flag.

Honestly, I want to stop. But I can’t. Just one more…

What’s the best thing about Switzerland?
I don’t know, but the flag’s a big plus.

Okay, seriously… I didn’t invite you here today to listen to bad jokes. (Well, that’s not the only reason, anyway.)

I invited you here today to have a little Flag Day fun with math. The projectionist Shahee Ilya has converted the flag of every country into a pie graph based on its colors. For example, the Austrian flag has two red stripes and one white stripe, so it is converted to a pie graph as follows:

Austria Flag Hand Right Arrow Austria Pie Chart

Pretty cool, huh?

What follows are pie graphs for ten flags. Even if you are geographically challenged, I assure you that you’ve heard of all ten countries represented below. Can you name the country whose flag was used to create each pie graph?

Flag1 Flag2
Flag3 Flag4
Flag5 Flag6
Flag7 Flag8
Flag9 Flag10

 

Stumped by the challenge? Here’s a hint: The countries whose flags are represented above are the ten most populous countries on Earth. (Admittedly, had someone asked me to name the ten most populous countries prior to writing this post, I would have been lucky to identify half of them.)

And just to put some space between the pie graphs above and the countries whose flag they represent below (i.e., the answers), I include for your enjoyment one of the most hideous puns you’ll ever see, modified from an even worse version at Six Puns:

During a recent heat wave, a poll revealed that beads of sweat had amassed (mast) on the secretary’s forehead and a virus was rippling through the office staff. Although the boss knew that the secretary was very sick, he saw no reason to ban her from the office. Instead, he wrote a note with pennant (pen and) paper, and he flagged the issue to be addressed with the standard protocol.

If you tolerated that, you certainly deserve the answers…

Nigeria Pakistan
Russia United States
Indonesia Japan
Bangladesh Brazil
China India
