QuestionAnswer
Area the measure of the interior surface of a two-dimensional figure.
center the point from which all points on a circle are the same distance
circle the set of all points in a plane that are the same distance from a given point called the center
circumference the distance around a circle
composite figure Figures that have the same size and same shape and corresponding sides and angles with equal measure.
diameter The distance across a circle through its center
face A flat surface of a polyhedron
lateral faces its a polyhedron, a face that is not a base
pi the ratio of the circumference of a circle to its diameter. the Greek letter pi represents this number. the value of pi is 3.1415926... Approximations for pi are 3.14 and 22 over 7
prism A polyhedron with two parallel congruent faces called bases
pyramid A polyhedron with one base that is a polygon and three or more triangular faces that meet at a common vertex
radius The distance from the center of a circle to any point on the circle
regular pyramid A pyramid whose regular polygon and in witch the segment from the vertex to the center of the base is the altitude.
semicircle Half of a circle. the formul for the area of a semicir
slant height The height of each lateral face.
surface area the sum of the areas of all the surfaces(faces) of a three-dimensional figure.
volume the number of cubic units needed to fill the space occcupied by a solid.
