Using Pi in Calculations
Comments(1)I hope you had a good weekend. As promised today I will talk about using Pi in calculations.
You can call up Pi in the CAL command by simply typing “pi” (without quotation marks).
For example, if a circle has a radius of 5 units, you could calculate the area or circumference in the methods shown below. Type CAL on the command line and at the Expression prompt type one of these formulas:
..to calculate area:
pi*5*5
…or:
pi*sqr(5)
…to calculate circumference:
pi*10
…or:
pi(5*2)
