Problem

A hollow cylindrical pipe has length

L = 5\,\text{m}

, inner radius

r_{1} = 8\,\text{cm}

, and outer radius

r_{2} = 10\,\text{cm}

. Current flows along the length of the pipe (longitudinally, not radially). Calculate the resistance if the material resistivity is

\rho = 3.14 \times 10^{-6}\,\Omega\cdot\text{m}
