11.3 Surface Areas of Pyramids and Cones A pyramid is a polyhedron in which one face (the base) can be any polygon and the other faces (the lateral faces) are triangles that meet at a common vertex (called the vertex of the pyramid). Pyramids The altitude of a pyramid is the perpendicular segment from the vertex to the plane of the base.
The length of the altitude is the height of the pyramid. A regular pyramid is a pyramid whose base is a regular polygon and whose lateral faces are congruent isosceles triangles. The slant height is the length of the altitude of a lateral face of the pyramid. Lateral and Surface Areas of a Pyramid 1 L. A. P
2 S . A. L. A. B Cones A cone is a solid that has one base and a vertex that is not in the same plane as the base. The base of a cone is a circle. In a right cone, the altitude is the perpendicular segment from the vertex to the center of the base. The height, h, is the length of the altitude.
The slant height, , is the distance from the vertex to a point on the edge of the base. Surface Area of a Cone S . A. L. A. B S . A. r r 2 (15)(25) (15)
Modeling interaction between predictors Recall that the multiple regression model E(y) = a + b1x1 + b2x2 + …. + bkxk assumes the partial slope relating E(y) to each xi is the same at all values of other predictors (i.e.,...
The tephigram and skew-T closely satisfy nearly all these criteria. The table below summarizes the important aspects for some diagrams. Note that the skew-T, which we will use in this class, exhibits most of the ideal properties.
