The Infinity Paradox Of Gabriel's Horn

The Infinity Paradox Of Gabriel's Horn

Gabriel's horn is made by rotating a graph of the function y = 1/x (when x is greater than or equal to 1) about the x-axis. Its surface area is infinite, but its volume is not-theoretically, the horn could be filled with pi cubic units of paint, whereas you'd need infinite paint to coat its surface.
