7.4 Objectives: Define and use the formula for the surface area of a cone Define and use the formula for the volume of a cone

Definitions: Cone: A 3D figure that has a cicular base Base: Fave that are formed by a circular figure and its translated image Lateral face: Curved faces Altitude: A segment that has endpoints and the tip of the cone and the base of the figure that is perpendicular to the base Height: The length of the altitude RIght cone: A cone that has a altitude that intersects the base in the center Slant height of a cone: length of the altitude on the lateral faces

Surface area of a right cone: S=(pi)rl+(pi)r² with L equaling the slant height of the figure
