How can I calculate the cross-section of a conductor based on diameter, length and resistance ??? Is there a formula I can use to calculate something like this?

d = 1.43mm
R = 4287.3 ?
l = 1m
? = R * S / l = 4287.3? * (1/4 * ? * (1.43mm ^ 2)) / 1m = ~ 6.886 * 10 ^ (- 3) ?m
Spore resistance of this cable, besides, it is not known what steel, what temperature.

I know what I have calculatedand I wrote it well - I wrote (or actually commented) about _resistance_ R = 4287.3? given earlier by col. lucasek (because a 1m steel wire with a diameter of 1.43mm with over 4k? is a bit much ...)
