Gabriel's Horn: Finite Volume, Infinite Surface

5 min21 december 2025

A deep dive into Torricelli's trumpet, the shape formed by revolving y = 1/x about the x-axis from x = 1 to infinity. We explore why its volume is finite (π) even as its surface area diverges to infinity, unravel the painter's paradox, and see how calculus resolves the mystery. We'll also discuss why the paradox disappears in the real world due to physical thickness and limits, and touch on the related fact that finite surface area for surfaces of revolution implies finite volume.
