The SQRTPI function in MS Excel is used to calculate the square root of a given numeric value multiplied by the value of Pi. The supplied numeric value is multiplied first with the value of Pi before getting the square root.

**Syntax**: =SQRTPI(number)

SQRTPI( number ) = SQRT( number * π )

The SQRTPI function syntax has the following arguments:

**Number**– positive numeric value for which SQRTPI needs to be calculated

**Example**: Let’s look at some Excel SQRTPI function examples and explore how to use the SQRTPI function as a worksheet function in Microsoft Excel:

**Syntax**: =SQRTPI(A2)

**Result**:

Based on the Excel spreadsheet above, the following SQRTPI examples would return:

**Syntax**: =SQRTPI(A3)**Result**: 7.089815404

**Syntax**: =SQRTPI(A4)**Result**: 35.44907702

**Syntax**: =SQRTPI(A5)**Result**: 53.17361553

**Syntax**: =SQRTPI(A6)**Result**: 10.63472311

**Syntax**: =SQRTPI(A7)**Result**: 12.40717696

**Syntax**: =SQRTPI(A8)**Result**: 28.35926161

**Syntax**: =SQRTPI(A9)**Result**: 21.26944621

**Syntax**: =SQRTPI(A10)**Result**: 19.49699236

**Syntax**: =SQRTPI(A12)**Result**: #NUM!

**Syntax**: =SQRTPI(A13)**Result**: #NUM!

**Syntax**: =SQRTPI(ABS(A14))**Result**: 21.26944621

**Note**:

- #NUM!: This result is displayed if the supplied numeric value is less than 0.
- #VALUE!: This result is displayed if you have entered a non-numeric value.
- #NAME!: This result is displayed when the Analysis ToolPak add-in is not activated in your Excel spreadsheet. You are required to activate the add-in before you can use the SQRTPI function in MS Excel.
