Across
- 1. Only 3D shape that doesn't have a lateral area. Uses 4/3πr³ to find the volume.
- 4. Uses πrl for lateral area. For volume it uses ⅓ πr²h
- 5. Only has one base, and all triangles come from each edge that connect at one point at the top. To find the lateral area use
- 6. Used to calculate the area of a circle. Has an infinite number of digits.
- 7. Its the incline from a horizontal or vertical line; slant up or down. To find it use rise over run.
- 8. Is a 3D shape with 6 faces. All faces are squares.
- 9. the trigonometric function is equal to the ratio of the side opposite a given angle (in a right triangle) to the hypotenuse. Opposite over hypotenuse.
- 11. the trigonometric function that is equal to the ratio of the side adjacent to an acute angle (in a right-angled triangle) to the hypotenuse. Adjacent over hypotenuse
- 13. A straight line or plane that touches a curve or curved surface at a point, but if extended does not cross it at that point. Always creates a right angle.
- 16. It is a 2D shape. Only has 3 sides.
- 17. The area of all the side except for the base. Doesn’t include the base.
Down
- 2. Uses ph to find the lateral area. Has two bases
- 3. Two circle bases. Has a volume formula of πr²h.
- 6. The distance around the edge of a shape. Uses addition
- 7. The area of all the sides of a 3D figure. Includes the base.
- 8. Has a single circle base. Has 1/3 of the room of a cylinders.
- 10. The intersection point of two sides of a plane figure. The highest point; the top or apex.
- 12. a polygon with 5 sides. Also has 5 angles
- 14. the amount of space within the perimeter of a 2D shape. Uses multiplication.
- 15. the amount of space that a substance or object occupies. The amount of space inside an enclosed area
