The diameter.
The diameter symbol (⌀) is used to indicate the diameter of a circle or cylindrical object, typically in technical drawings, engineering specifications, and manufacturing contexts. It is often placed before the numerical value to clearly specify the diameter measurement, such as ⌀10 mm. Use the symbol when precision is required in dimensions, especially in fields like architecture, mechanics, and product design.
In architectural or engineering drawings, it is the symbol for diameter
It is defined as the ratio of the circumference of a circle to its diameter

What exactly do you mean by "outside" diameter? C=d(3.14) This is supposed to be the symbol pi but I didn't know how to do it on my computer.
Use the formulae for the area and circumference of a circle, replacing the symbol for the radius or the diameter with the known radius or diameter. As a reminder, the radius is 1/2 the diameter.Circumference = pi x diameter area = pi x radius squared
Measure the diameter. Multiply the diameter by Pi, this will give the circumference. Pi is approximately 3.1415927 You can use the Pi symbol on a scientific calculator or use 22/7.
The symbol you are referring to is likely the "caret" symbol, which is commonly used to indicate exponentiation in mathematical expressions. It is not a standard mathematical notation for representing the number Pi.
pi is represented by the Greek letter (of the same name) π and is the ratio of the circumference of a circle to its diameter.
π - the ratio of a circle's circumference to its diameter.
