## Homework Statement

A material of resistivity p is formed into a solid, truncated cone of height

h and radii r_1 and r_2 at either end. Calculate the resistance of the cone

between the two flat ends.

You can find my awful sketch as a thumbnail.

## Homework Equations

R=pL/A ,where p is resistivity.

## The Attempt at a Solution

I know I need to calculate dR=(p*dy)/(pi*r^2). But I don't know what is r as a function of y.
