RADIANS Function in Excel is a mathematical formula that helps to calculate the angle in radians based on the angle measured in degrees. It is a useful tool to use when dealing with angles and lengths in geometry problems. It can also be used to convert degrees to radians and vice versa.

To use the function enter the angle measure in degrees. This will then return the angle measure in radians. The function converts angles in degrees to angles in radians. This is done by multiplying the angle measure in degrees by pi divided by 180.

For example, if the angle measured in degrees is 45, the corresponding angle measured in radians is 0.7854. The Radians Function is also used for geometry problems. Angles are often measured in radians as opposed to degrees, making the function a very useful tool. It is used to convert the angle measure in degrees to the angle measure in radians, allowing the user to solve the problem more easily.

The Radians Formula is useful in converting the circumference of a circle to its radius. This is done by multiplying the circumference by the inverse of pi divided by 180. This is then used to calculate the radius of the circle from the circumference.
