A flag is formed by the region bounded by y ≤ x + 3, y ≤ −2x + 12, and the x-axis. Find 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.
