How To Multiply By Pi In Excel
Excel PI Function
Summary
The Excel PI function returns the value of the geometric constant π (pi). The value represents a half-rotation in the radian bending system. The constant appears in many formulas relating the circle, such as the area of a circle.
Usage notes
The PI function returns the value of π (pi) accurate to 15 digits. The value of π represents a half-turn in radians and appears in many formulas relating to the circle. The PI function takes no arguments:
= PI () // returns three.14159265358979
Circumference of a circle
The constant π appears in many math formulas relating to the circle. The formula for the circumference of a circle is 2πr. Given a radius of 3, the same formula in Excel is:
= ii * PI () * 3 // circumference of circle, r=3
Expanse of a circle
The surface area enclosed past a circumvolve with radius (r) is defined by the following formula: πrtwo. With radius in jail cell A1, the same formula in Excel with the PI() part is:
Radians to degrees
To convert an angle measured in radians in terms of π, the DEGREES function can be used to get the corresponding bending in degrees:
