lesson 11-3 Flashcards
1
Q
pyramid (vertexes + L faces + slant height)
A
polyhedron whose base is a regular polygon and lateral faces are triangles. LA’s all have a common vertex. slant height is the altitude of the lateral faces
2
Q
regular pyramid
A
a pyramid whose base is a square and lateral faces that are isosceles triangles.
3
Q
LA pyramid
SA pyramid
A
LA = 1/2 perimeter + slant height
SA = LA + base area
4
Q
cone (+slant height)
A
polyhedron with a circular base and vertex that is not in the same plane as the base. slant height is the distance between the vertex and a point on the edge of the base.
5
Q
right cone
A
a cones whose altitude from the vertex to the bases is perp.
6
Q
LA cone
SA cone
A
LA = 1/2 * 2piradius * slant height
SA = LA * base area
