A cylindrical aluminum pipe of length $1.40\mathrm{m}$ has an inner radius of $2.15\times 10^{?3}\mathrm{m}$ and an outer radius of $3.88\times 10^{?3}\mathrm{m}$. The interior of the pipe is completely filled with copper. What is the resistance of this unit? (Hint: Imagine that the pipe is connected between the terminals of a battery and decide whether the oluminum and copper parts of the pipe are in series or in parallel.) Number Units
