  1. 12.2 b Surface Area of Prisms and Cylinders State Standards Lesson Goals Find the surface area of a cylinder. 8, 9: Solve problems involving the surface area lateral area of geometric solids and COMMIT TO MEMORY THE NECESSARY FORMULAS.

  2. definitions Cylinder • Bases: two congruent-parallel circles • Lateral face: a rectangle connecting the bases • Altitude: the perpendicular distance between its bases.

  3. definitions • Surface area: The sum of the lateral area and the area of the two bases. • Lateral area: the area of the curved surface.
