If you only know the length, and nothing else, you can't. If you know the length and the volume, you can calculate the diameter.

If you know the circumference, the ration of the diameter to the circumference is π, so diameter = circumference/π If you have the radius, diameter = 2 x radius

To get the diameter d is to divide the circumference C by pi. d = C / pi

There is no such formula.

Depends on what you know. Like if you know the radius, square it and multiply it by pi. If you know the diameter, do the same thing as you do with the radius except do it after finding half of that diameter.
