The diameter.
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
Archimedes
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.
"Pi" is the symbol almost always used to represent the ratioof the circumference of any circle to its diameter.
