Is this an ohms law problem? Please walk me through this one. I am very grateful.

A cylindrical copper cable carries a current of 1200 A. There is a potential difference of 16 mv between the two points on the cable that are 24 cm apart. The number of carriers per unit volume of the current in the wire is 28 6.95 x 10^28th power.

Find the radius of the cable.

Find the average current density in the cable.

Find the drift velocity of the current.
