Determining drift velocity of electrons at specific temperature

[mlbqd3]

Homework Statement

A gold conductor with an electric field of 0.01 V/m applied, is 0.01 m long and 5.0E-5m in radius. Assuming one conduction electron per atom, what is the drift velocity of the electrons at a temperature of 20.0 degrees C? at 50 degrees C?

Homework Equations

I know that R=rho(L/A), but I have no idea where to go from here. If someone could give me an idea how to connect the length and area to drift velocity I would appreciate it.
