 Uniform Lamina Of course. Drag your mouse over the answer in my last post. Fermat
 Uniform Lamina Surely, if you have a question like that, you know the basic formulas. The y-coordinate of the centroid of a region (center of mass assuming uniform density) is . is, of course, the area of the region. Once, when I was teaching this, a student became fascinated by the word "lamina" (had never seen it before, apparently). As the last question on the final exam, I asked "What is 'lamina' spelled backwards?" Another student became furious with me because "That question doesn't make any sense!" HallsofIvy
