Cones and Spheres

EngageNY 45 min(s)

Students use the Pythagorean theorem to determine an unknown dimension of a cone or a sphere. Students know that a pyramid is a special type of cone with triangular faces and a polygonal base. Students know how to use the lateral length of a cone and the length of a chord of a sphere to solve problems related to volume. The purpose of these exercises is for students to perform computations that may help them relate the volume formula for a pyramid to the volume formula for a right circular cone, introduced in Module 5.
