How to use SQRTPI Google Sheets formula?

The syntax for the SQRTPI formula is =SQRTPI(value), it has 1 required parameter.

Why is SQRTPI Google Sheets formula not working?

One common reason the SQRTPI formula may not be working is due to not multiplying the input by pi. One common mistake when using the <code>SQRTPI</code> function is forgetting to multiply the input by pi before taking the square root.

SQRTPI

The SQRTPI function returns the square root of the product of a supplied number (value) and pi (3.14159265359). This function is useful in geometry and trigonometry calculations where the area and circumference of circles are used.

=SQRTPI(value)

Parameters:

value (required):
The number to be multiplied by pi and then the square root taken.

Examples

Here are a few example use cases that explain how to use the SQRTPI formula in Google Sheets.

Calculate the circumference of a circle

To calculate the circumference of a circle, multiply the diameter by pi. The SQRTPI function can be used to simplify this calculation by taking the square root of the product of the diameter and pi: =2*SQRTPI(diameter/2).

Calculate the area of a circle

To calculate the area of a circle, square the radius and multiply by pi. The SQRTPI function can be used to simplify this calculation by taking the square root of the product of the radius squared and pi: =SQRTPI(radius^2).

Calculate the standard deviation of a set of values

The SQRTPI function can be used to calculate the standard deviation of a set of values. The formula for the standard deviation is the square root of the variance. The variance is the average of the squared differences from the mean. Therefore, the standard deviation can be calculated as follows: =SQRTPI(AVERAGE((values - AVERAGE(values))^2)).

Common Mistakes

SQRTPI not working? Here are some common mistakes people make when using the SQRTPI Google Sheets Formula:

Not multiplying the input by pi

One common mistake when using the SQRTPI function is forgetting to multiply the input by pi before taking the square root.

Providing a negative input

The SQRTPI function only works with positive inputs. Providing a negative input will result in an error.

The following functions are similar to SQRTPI or are often used with it in a formula:

PI
The PI() function returns the value of pi to 10 decimal places, which is approximately 3.1415926536. This function is often used in geometry and trigonometry calculations.
SIN
The SIN function in Google Sheets returns the sine of a given angle in radians. Sine is a mathematical function that describes a smooth repetitive oscillation. It is commonly used in trigonometry, physics, and engineering to model phenomena such as waves, oscillations, and periodic motion.
COS
The COS function in Google Sheets returns the cosine of an angle provided in radians. It is commonly used in trigonometry to calculate the cosine of an angle. The function takes one parameter, the angle in radians.
