which calculates the volume of a sphere with the radius given in column B. Units are indicated generically with “u”, and the result is units cubed (u3). Where r represents radius, and 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: To cube a number in Excel, you can use the exponentiation operator (^): Or, you can use the POWER function: Rewriting the formula using 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.
