Consider the curve y = 1 for x > 1. (a) Determine the volume created by revolving the area under this curve and above the x-axis around the x-axis. This means setup and evaluate an integral for the volume. (b) Show using Comparison Test that the surface area of the shape created by revolving this curve around the x-axis diverges to infinity.

I just need this checked and corrected please
![In this question you'll investigate an infinite 3D shape known as Gabriel's Horn.
This shape strangely enough has a FINITE volume but an INFINITE surface area.
Consider the curve y = 1 for x > 1.
(a) Determine the volume created by revolving the area under this curve and above the x-axis
around the x-axis. This means setup and evaluate an integral for the volume.
(b) Show using Comparison Test that the surface area of the shape created by revolving this
curve around the x-axis diverges to infinity.
