(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A number 16 copper wire has a diameter of 1.291mm. Calculate the resistance of a 43m long piece of such wire. Use rho=1.72x10-8 Ohm-m for the resistivity of copper. Use units of "ohm".

2. Relevant equations

R=pl/A

rho is the same thing as the p

3. The attempt at a solution

I just dont know the equation for find A. if you can help me with that then this should be simple since both p and l are given as well as d.
