WebPolyhedrons are space figures with flat surfaces, called faces, which are made of polygons. Prisms and pyramids are examples of polyhedrons. Cylinders, cones, and spheres are not polyhedrons, because they have curved, not flat, surfaces. A cylinder has two parallel, congruent bases that are circles. WebExplanation: . The formula for the volume of the polyhedron is: where is the radius of the cone, is the height of the cone, is the radius of the cylinder, and is the height of the cylinder. Use the formula for a triangle to find the length of the radius and height of the cone: Plugging in our values, we get:
