  1. how my name is Jeff, and I think math is
  2. useless and dumb.
  3. Well, Jeff, why do you think math is useless and
  4. dumb? Because it is Well, Jeff, what if I were
  5. to tell you that you could find the volume of
  6. the roof of a house?
  7. If you're an architect?
  8. Oh, well, the done.
  9. Yeah, it really is cool.
  10. So let's learn how to find the volume of a
  11. cone. So let's get started.
  12. Step one.
  13. We need to know that the formula of the volume
  14. of a cone is one third times pi times the
  15. radius Where then we multiply that by the height.
  16. Then let's find out what the radius is.
  17. As you can see, they give the diameter to us,
  18. which is 22.
  19. The radius is just half the diameter, so we just
  20. divide 22 by two, which is 11.
  21. Yeah, Step three.
  22. Let's plug the numbers in.
  23. We got now one third times 3.14 which is pi
  24. 11 squared times 10.
  25. But we got to simplify 11 square to what 11
  26. squared is just 11 times 11, so 11 times 11
  27. is 1 21.
  28. Let's multiply out on 21 times 10 is 1210 1210
  29. times pi or 3.14 is 3007 and 99.4.
  30. What do we do this with this 3007 or 99.4?
  31. What we divide by three.
  32. Wait, Didn't I say that you multiply it by one
  33. third? Well, multiplying by a fraction is the same thing
  34. as dividing it.
  35. So we just divide by three.
  36. 30,799 0.4 to 5 by three is 1266.46 and a
  37. bunch of digits.
  38. Well, I think we should round that just to make
  39. it simpler.
  40. So we were rounded to the nearest 100.
  41. It is 1256.47 Makes it a lot simpler, doesn't it?
  42. And now we know how to find the volume of
  43. a cone.
  44. It the answer is 1256.47 millimeters squared.
  45. Fun fact.
  46. The volume of this Kona is only 4.33% of the
  47. United States liquid gallon.
  48. The cone must be like this small.
  49. Now we know how to find the volume of a
  50. cone. Uh huh.
  51. Wow, That is what?
  52. It's actually really cool.
  53. I really learned a lot.
  54. Yeah. Yes.
  55. I think everybody learned a lot.
  56. Yeah. I hope this tutorial was used to you guys
  57. and I'll catch you guys next time.
  58. Bye.
