In geometry, the formula for calculating the volume of a cylinder is:
The Greek letter π ("pi") represents the ratio of the circumference of a circle to its diameter. In Excel, π is represented in a formula with the PI function, which returns the number 3.14159265358979, accurate to 15 digits:
=PI() // returns 3.14159265358979
To square a number in Excel, you can use the exponentiation operator (^):
Or, you can use the POWER function:
Rewriting the formula for volume of a cylinder with Excel's math operators, we get:
Or, with the POWER function:
The result is the same for both formulas. Following Excel's order of operations, exponentiation will occur before multiplication.
