In this lesson we are going to go over surface area of pyramids and cones. In previous lessons we have learn what are pyramids. Pyramids have only one base and lateral faces always form triangles. The altitude is the segment from the vertex perpendicular to the base. A regular pyramid is when the base is a regular polygon, for example a square. You'll learn the formulas for the lateral area of a regular pyramid, and also its surface area. The base of a cone is a circle. The axis of a cone would be the segment from the vertex down to the center of the circle. This lesson covers right cones and their lateral and surface areas.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
