To multiply a value by pi in Excel, you can use the PI() function within a formula. The PI() function returns the value of pi (approximately 3.14159265358979).
Using the PI() Function
Here's how to multiply a number by pi in Excel:
- Select the cell where you want the result to appear.
- Enter the formula using the
PI()function.
Here are a few examples:
- Multiplying a number directly: To multiply 5 by pi, enter the formula
=5*PI()into the cell. The cell will display the result of 5 multiplied by pi (approximately 15.70796327). - Multiplying a cell value by pi: If cell A1 contains the number you want to multiply by pi, enter the formula
=A1*PI()into the cell where you want the result. This will multiply the value in cell A1 by pi. - Using PI() in more complex equations: You can use
PI()as part of a larger formula. For example,=PI()/2calculates pi divided by two.
Examples in a Table
| Formula | Description | Example Result (approximate) |
|---|---|---|
=PI() |
Returns the value of pi. | 3.141592654 |
=5*PI() |
Multiplies 5 by pi. | 15.70796327 |
=A1*PI() |
Multiplies the value in cell A1 by pi. (Assuming A1 contains 10) | 31.41592654 |
=PI()/2 |
Divides pi by 2. | 1.570796327 |
Key Takeaways
- The
PI()function is a built-in Excel function that returns the value of pi. - To multiply any number by pi, use the formula
=number*PI(), replacing "number" with the actual number or a cell reference containing the number. - You can integrate the
PI()function into more complex formulas as needed.
