  1. 2. Distance around (perimeter) of a circle = 2πr or πd
  2. 6. V = 1/3 Bh or Bh/3
  3. 7. Mode the calculator must be in to find angles in degree (NOT RADIANS) from trig ratios.
  4. 8. An acronym helping one remember the 3 basic ratios of sides in a right triangle; SIN=O/H, COS=A/H, TAN=O/A
  5. 10. ½ bh or bh/2 (half the area of a rectangle)
  6. 11. Finding measures of all the sides and all the angles of a triangle
  7. 15. If you know a trig ratio, you can use the Ti-Nspire calculator to find the angle in degrees.
  8. 19. A = lw or bh (base X height)
  9. 20. SA = 4 πr^2
Down
  1. 1. A formula for finding the 3rd side of a right triangle when 2 of the sides are known. The sum of the squares of the legs
  2. 3. V = Bh (where B is area of rectangular base)
  3. 4. Any whole numbers that satisfy the Pythagorean Theorem, example, 3, 4, 5.
  4. 5. Volume of a sphere = 4/3 πr^3 or 4 πr^3 / 3
  5. 9. V = Bh (where B is area of triangular base, bh/2, and the h is the height of the figure)
  6. 12. SA = 2 πr^2+2πrh
  7. 13. A = πr^2
  8. 14. If the occurrence of A does not affect the occurrence of B
  9. 16. A is not a prism since its “sides” are not flat, but the formula is the same,V = Bh or V = πr^2h
  10. 17. If the occurrence of one event affects the probability of the other.
  11. 18. V = Bh (where B is area of square base or s^2, so V = s^3
