Common Use Case: 
Calculate Circumference or Area of a Circle

If anyone knows what else you can do with pi, please let me know. In the meantime.. circles.

Circumference

Calculating the length of a circle's boundary.

prop("Radius") * 2 * pi
  • prop("Radius") → Specifies the property you wish to use as the radius (make sure it's a Number property).
  • * 2 → Multiplies the radius by 2.
  • * pi → Multiplies the result of the above by pi (3.14...).

Area

Calculating the area of a circle.

prop("Radius") * prop("Radius") * pi
  • prop("Radius") → Specifies the property you wish to use as the radius (make sure it's a Number property).
  • * prop("Radius") → Multiplies the radius by itself.
  • * pi → Multiplies the result of the above by pi.
