Explanation
In geometry, the formula for calculating the volume of a cone is:
The formula for calculating the volume of a cone is based on the formula for calculating the volume of a pyramid. Since the base of a cone is a circular, the formula for area of a circle is included.
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 (^):
=A1^2
Or, you can use the POWER function :
=POWER(A1,2)
Rewriting the formula for volume of a cone with Excel’s math operators , we get:
=1/3*PI()*B5^2*C5
Or, with the POWER function:
=1/3*PI()*POWER(B5,2)*C5
The result is the same for both formulas. Following Excel’s order of operations , exponentiation will occur before multiplication.
