Homework Help: Physics

What is the resistance of a 4.00 m length of copper wire having a diameter of 2.00 mm at a temperature of 20 degrees?

R= ?
L= 4.00 m
resistivity= 1.72 * 10^-8 ohm-meters
A= ?

A= pi*r^2
change 2 mm to .002m, square it and multiply by 3.14
I got .00001256

Is this right so far?
