When using pi, do you use 3.14 or 3.141592653?

You would usually use 3.14

Step-by-step explanation:

It kind of depends on where you are using it. In an equation, pi would be used as 3.14 and the answer would be approximated. To write it anywhere else (I dont know where else you would though), you would do the pi symbol. I hope this helps.

i always use 3.1415 but just to be safe use the pi symbol  :)
