| 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 givien points in a plane that are the same distance from a givien point called the center |
| Circumference | the distance around the circle |
| Composite figures | a figure that is made up of two or more figures |
| Compostie solids | 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 prism that has two parallel congruent bases that are rectangles. |
| 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. |
