1-172.

A flag is defined by the region between the -axis and the function listed below. Sketch the flag and calculate the volume of the solid generated by rotating the bounded region about the

*-axis. To help you visualize this, use the 1-172 eTool (Desmos). Homework Help ✎*

When rotated around the -axis, it is a cylinder next to a cone, so volume is:

Use the eTool below to visualize the flag.
