Solving Current: Copper Cylinder Density & Electron Count

[sbp_387]

I need help solving a problem
A 60 g hollow copper cylinder is 10 cm long and has an inner diameter of 1.0 cm. The current density along the length of the cylinder is 170,000 A/m^2. What is the current in the cylinder?

the electron density for copper is 8.5E28

thanks for your help
