Did you have pi memorized, or did you look it up first? I've managed to remember the 3.14 part since 10th grade, but anytime I want more precision (which, now that I think about it; has been NEVER) I look it up. :joke:

[Bob Denman]

I actually keep it memorized back to six decimal places...
It comes in REAL handy, for playing with engine displacement equations! nojoke :thumbup:

Just wait till you want to build a round house...:joke:

Um, shouldn't there be a "e" at the end..:roflblack:

Way back--(1970's) I had a mathematics professor that was using the University "super computer" to determine the actual #. At that time he said the number covered thousands of pages--and he was still running the program. I believe he was writing some kind of paper on the subject. A little to academic for me. :roflblack::roflblack:

Bob, you want engine displacement, .7854 X bore squared X stroke X number of cylinders. Forget Pi.

I always kind of liked "Pi times (r Squared), times the stroke of the engine, to give the cylinder's displacement...
I'll try yours on for size... Thanks! :thumbup:

[shelbydave]

For engine displacement, I just fill it with water, and then tip the engine over and pour it into a measuring cup.... I guess just doing the math might be easier on the back. :)

Now pi predates Albert E. so what is the relevance? Some one told me the date but that won't be until next year.

Does your calculator have a pi key?

[bruiser]

I knew the 3.14 but long forgot the rest, so yes, I had to look it up.

pi divided by 4 = .7854

[Bob Denman]

Does your calculator have a pi key?
Nope! :D

[Dan_Ashley]

Nope! :D
cheap too

I'm building a geodesic dome on top of the round house............................................. who wants a round house like everyone elses? .

Pyramids; Baby! :D :2thumbs:
