Surface Areas and Volumes of Cones - Lesson 11.6

Learn surface area and volume calculations for cones in this comprehensive mathematics lecture and problem-solving session. Master the surface area formula SA = πrl + πr^2, understanding both the lateral area (party hat wall) and circular base components. Explore the volume formula V = (1/3)πr^2h, drawing connections to pyramid and cylinder formulas while discovering that three cones can fill a cylinder of equal base area and height. Work through 26 detailed problems covering various applications, including volumes of similar solids and composite figures. Access accompanying textbook materials and benefit from thorough explanations of each problem, including a special focus on challenging frustum calculations with additional supplementary content for complex problems. Follow along with clearly marked timestamps for each section, making it easy to review specific concepts or problems as needed.
