Gabriel's horn. Gabriel's horn is the solid obtained by rotating around the x-axis the infinite region bounded
by the curve y = 1, the line x = 1 and the z-axis.
(a) Find the volume enclosed by Gabriel's horn.
(b) It is given that the surface area of Gabriel's horn is given by
= 1,08 = = √V/
S = 2π
dr
Use a comparison test to determine whether this integral converges or diverges. If it converges, find its value.
(c) Explain why the results from parts (a) and (b) are counter-intuitive.
