It depends on the accuracy you need. A pretty rough procedure would be:
1. Find the F(r,z) = 0 line with ContourPlot
2. Extract the Line object from the ContourGraphics using Parts.
3. Create an InterpolatingFunction of the type:
r = f[z]
4. compute the volume:
2 Pi Integrate[ r , {r, 0, f[z]} , {z, 0, zmax} ]
Hope that helps !
