  1. 1. Only 3D shape that doesn't have a lateral area. Uses 4/3πr³ to find the volume.
  2. 4. Uses πrl for lateral area. For volume it uses ⅓ πr²h
  3. 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
  4. 6. Used to calculate the area of a circle. Has an infinite number of digits.
  5. 7. Its the incline from a horizontal or vertical line; slant up or down. To find it use rise over run.
  6. 8. Is a 3D shape with 6 faces. All faces are squares.
  7. 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.
  8. 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
  9. 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.
  10. 16. It is a 2D shape. Only has 3 sides.
  11. 17. The area of all the side except for the base. Doesn’t include the base.
Down
  1. 2. Uses ph to find the lateral area. Has two bases
  2. 3. Two circle bases. Has a volume formula of πr²h.
  3. 6. The distance around the edge of a shape. Uses addition
  4. 7. The area of all the sides of a 3D figure. Includes the base.
  5. 8. Has a single circle base. Has 1/3 of the room of a cylinders.
  6. 10. The intersection point of two sides of a plane figure. The highest point; the top or apex.
  7. 12. a polygon with 5 sides. Also has 5 angles
  8. 14. the amount of space within the perimeter of a 2D shape. Uses multiplication.
  9. 15. the amount of space that a substance or object occupies. The amount of space inside an enclosed area
