5-109.

A flag is formed by the region bounded by $y = x + 3$,  $y=-2x+12$, and the x-axis. Calculate the volume of the solid formed by rotating the flag about the x-axis. Homework Help ✎

Sketch the graph and outline the flag. Notice that the resultant volume will be two cones each with radius 6, but different heights.
