Pie =????????????????????.??
maria [59]
Hello there!

I can assume you mean "Pi".

Pi is an irrational number that has an infinity decimal, also known as a terminating decimal, which means to repeat infinitely.

The summarized form of Pi is 3.14, but since you have multiple units, I can assume you want the extended form.

Here it is:
3.14159265359

I hope this helps!
