What is "Pi" ?

I have alway used 3.1415 as pi. For what I was doing, four decimal places provided adequate precision.

Stop making me do math .

Five decimal places is probably the most you need. 8 or so is enough for inter-planetary travel. Beyond that it's basically just a competition.

Pi is the sixteenth letter of the Greek alphabet. (Count them.) I have always used 3.1416 since the next digit is 9, not that it makes that big of a difference.

100 digits of Pi : 3.1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825 3421170679. In 2019, we calculated 31.4 trillion digits of π — a world record at the time. Then, in 2021, scientists at the University of Applied Sciences of the Grisons calculated another 31.4 trillion digits of the constant, bringing the total up to 62.8 trillion decimal places. Pi is infinite number so yeah...

π is an irrational number, which means that it cannot be expressed as a fraction and has an infinite number of decimal places. 3.14 and 22/7 are approximations of π. Incidentally, π is the 16th letter of the greek alphabet.

Shiboge, Infinite pies sound good to me . But only in varying flavours .

Yes I remember being taught pi as 22/7.

It is pi and not pie as I just commented.

Pie is an infinite number. I think most common is to go with 3.14 as good enough but it is the actual fraction of 22/7. Twenty two over seven.

easy math???

Player #3577148, Pi is the 11-th letter in greek alphabet, is not a paella starter nor 3,414. So which was your correct answer?

My answer was correct and appeared that it was wrong
