ACT 3D Surface Area — Tutor Intake Assessment

This is a spot-check intake on surface area of prisms, cylinders, pyramids, cones, and spheres. The goal is to find where your understanding breaks down so we can plan instruction — not to grade you. Work as you would on the ACT (no formula sheet). If you don't see how to start a problem, move on and we'll discuss it together.
