A current of one ampere is flowing through a wire. Calculate the number of electrons flowing through the cross-section of the wire per second?

A copper wire of diameter 2/(3sqrtpi)mm is carrying a current of 1 amp. Calculate the number of free electrons which flow past any cross section of the wire per sec Also find the average speed with which free electrons are flowing in the copper wire assuming that there is one free electron per atom of copper. Number of atmos per cm^3 of copper =9 times 10^22 , electronic charge =1.6 times 10^-19 coulomb.
