For those whose calculators don’t have a pi key, use 355/113.

Or one could just memorize the returned value of 3.1416...without having to memorize 6 digits and an operation...as was SOP in pre-calculator days.

But then again I learned that in the olden times when trig tables were used on the job.

No batteries to worry about.

Well, I had a pi designation on my slide rule, too.

The 355/113 is astonishingly close to the value of pi, and that accuracy will suffice to many more digits than five or six.
