| 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 the 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,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 22/7. |
| 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 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=1/2 pi r squared. |
| 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 in cubed of ft cubed. |
