SUMMARY
The discussion focuses on calculating the center of mass for a triangular plate with vertices at (1,0), (0,0), and (1,1), with a density of 12. The Pappus Centroid Theorem is applied to determine the volume of the solid formed by rotating this triangle around the vertical line x = -2. Participants clarify that graphing is not necessary for solving the problem, emphasizing the geometric properties of the triangle and the rotation axis.
