The space between two concentric spherical-shell conductors is filled

with a material that has a resistivity of 10^9 ohm meter. If the

inner shell has a radius of 1.5 cm and the outer shell has a radius of

5 cm, what is the resistance between the conductors?

I found a hint that says to find the resistance of a spherical shell

element of the material of area 4(pi)r^2 and length dr, and integrate

to find the total resistance of the set of shells in series.

Any help would be great! thanks
