Quick question about the body display rotation?

What shape is formed when the area between the functions 8 and xy = x + y = 9 is rotation around the x axis? What wheels look like the cross? What are the terms of the cons-sectional area of the disk to FThe any point x in the interval of the rotation?

What should resemble the cross-sectional slices? As a segment of a cake that is not pizza at all perfectly round. What are the terms of the cons-sectional area of the disc at any point in FThe x distance from the rotation? Area = Int [1 8] (9-x) dx-int [1 8] (8 / x) dx Which form occurs when the area between the functions 8 and xy = x + y = Turned 9, the x-axis? The exterior is a truncated cone with a curved surface such that the inner segment of the pizza.
