Web17 feb. 2024 · In fact, Archimedes thought it was so wonderful that he had a carving of a sphere and a cylinder put on his tombstone. The surface area of a sphere is 4*pi*r^2. The lateral area of a cylinder is the height times the circumference of the base, or 2*pi*r*h. For a cylinder of height 2r, that makes S = 2*pi*r* (2r) = 4*pi*r^2 Whether you think it's ...
