| Question | Answer |
|---|---|
| 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 | A figure that is made up of two or more figures. |
| composite solid | An object made up of more than one solid |
| cone | A three-dimensional figure with one circular base connected by a curved surface to a single point. |
| cylinder | A three-dimensional figure with two parallel congruent circular bases connected by a curved surface. |
| diameter | The distance across a circle through its center. |
| face | A flat surface of a polyhedron. |
| hemisphere | One of two congruent halves of a sphere. |
| lateral face | In a polyhedron, any face that is not a base. |
| pi | The ratio of the circumference of a circle to its diameter. The Greek letter π represents this number. The value of pi is 3.1415926. . . . Approximations for pi are 3.14 and 227 . |
| 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 base is a regular polygon and in which the segment from the vertex to the center of the base is the altitude. |
| semicircle | Half of a circle. The formula for the area of a semicircle is A=12πr2 . |
| slant height | The height of each lateral face. |
| sphere | The set of all points in space that are a given distance from a given point called the center. |
| surface area | The sum of the areas of all the surfaces (faces) of a three-dimensional figure. |
| volume | The measure of the space occupied by a solid. Standard units of measure are cubic units such as in³ or ft³. |
