Gabriel's Horn

Gabriel's Horn

Vicente J. B.
The Gabriel's Horn is the surface of revolution of the function y=1/x about the x-axis for x>1 (it is represented 1<x<10). It has finite volume (pi) but infinite surface area. This leads to the paradoxical consequence that while Gabriel's horn can be filled up with pi cubic units of paint, an infinite number of square units of paint are needed to cover its surface!
