This article suggests the introduction of the concepts of areas bounded by plane curves and the volumes of solids of revolution in Pre-calculus. It builds on the basic knowledge that students bring to a pre-calculus class, derives a few more formulas, and gives examples of some problems on plane areas and the volumes of solids of revolution that could be solved at the pre-calculus level. More students will benefit from the exposure to these concepts, as not all pre-calculus students go on to take calculus. Furthermore, when students do get to calculus, they would have already acquired some skills in visualizing mental images or drawing sketches of solids of revolution.
