Pipe Diameter Tape Measure CONTEST for Pi Day 2022

 

Pipe diameter tape measure on National Pi Day
National Pi Day in the USA (Monday March 14, 2022)

What does a pipe diameter tape measure have to do with Pi Day? It’s a tape that you wrap around a pipe (the circumference), and it reads out the diameter for you. You don’t need to divide by pi (3.14159). It’s a simple but amazing tool for those that work with pipelines in oilfields and gas fields. Even arborists use them to measure the diameter of a tree trunk.

What does a “pie” have to do with this? 2 reasons. First, the two words sound the same. Second, pies are round, which is the appropriate shape when you are comparing circumferences and diameters.

So, enjoy the day by eating your favorite pie.

And now for the CONTEST:

Even if you’re not a mathematician, I think it’s safe to say that most people know the symbol .

But do you remember what it actually represents? Here’s a quick math lesson: It’s the ratio of a circle’s circumference (the distance around the circle) to its diameter (edge to edge, measuring through the center). Today is March 14th (3.14),  but most math nerds like to celebrate it as #PiDay!

  •  is constant for any circle, any size
  • Continues to infinity
  • In 1706 William Shaw, a Welsh mathematician, introduced the  symbol.
  • In 2010 a Japanese engineer and an American computer scientist broke the record for most digits calculated past the decimal: 5 trillion!
  • If you need to calculate the diameter of a tree trunk, pipe, or anything cylindrical, you will need a diameter tape measure. Just use it to measure the circumference, and it will calculate the diameter for you!
