The document discusses formulas for calculating the volumes of cones, pyramids, and spheres. It provides examples of applying these formulas, such as calculating the volume of ice cream in a cone 2 inches in diameter and 3 inches high. It also includes word problems about the volume of a trapezoidal pyramid and a snow cone.
