Find the volume of the given prism. Round to the nearest tenth. a) 2,028.0 yd3 b) 1,756.3 yd3 c) 3,512.6 yd3

9. Jake777

thanks for the 1 :)

10. Jake777

i need help with them all except the last 3

11. samnatha

q10 is 4189

12. Jake777

Thank u

13. samnatha

Q3 is 1,756.3 yd3 well i got 1762.8 so i wreckon its that

14. Jake777

oh ok ty for that 1 :)

15. samnatha

ok then for q7 i got 1092.72 so its close to 1,093.3 m3 so i dunno

16. Jake777

Yea that is the same answer i got for that 1 also that one was weird lol well ty for that one

17. Jake777

ty so much for helping me with these

18. samnatha

am no probs there is ome i haven't a clue on like but i will help with the ones i can :)

19. samnatha

Q5 is 768

20. Jake777

ty :) and also i appreciate that also...

21. samnatha

so for q6 i got root69 for h but then when i put all of it in the formula i got 276.8 so i dunno bout that one

22. samnatha

i haven't a clue how to the last 5 sorry

23. Jake777

V=1/3 (area of base) (height) to find h 13^2=10^2+h^2

24. samnatha

yea i got root 69 for h then the base is 10 by 10 so thats 100 then you put it all into the formula and i got 376.8 which isn't one of the options so not to sure bout that one

25. Jake777

oh i see what u mean now :-/

26. samnatha

yeah i mean if you did a 1/3 by 100 then u would get 33.3 which is an option but its not right so i dunno ..

27. Jake777

I guess ill go with that 1 because that is the only answer we can come up with ty with that one :)

28. samnatha

ok and for q4 i got a completely different answer..than whats there

29. Jake777

for 4 v=Pi^2h

30. Jake777

that was the hint i got which i think u know that lol

31. samnatha

yeah when i put all the ifo in so its like $\Pi \times 3.4^{2} \times 11 = 399.48$

32. Jake777

Hu that is weird i wonder y that happened

33. Jake777

i think for that question for what i got i think it is B which is 432.34 m^3

34. samnatha

i dunno either i'm going extremly wrong or you have a messed up paper :L

35. Jake777

Lol

36. Jake777

Dumb teachers lol

37. Jake777

38. samnatha

haha know how ye feel :L

39. samnatha

am hold on a sec i will try it now

40. Jake777

:)

41. Jake777

I think it is B i am like 55% sure so i want ur input on this one if u can...

42. samnatha

i got 81 fot that one do you want me to show u how i did it ?

43. Jake777

if u dont mind ya

44. samnatha

yeah no probs

45. Jake777

cool

46. samnatha

so to get the circumfrence of a circle it 2 by pi by r so you let that formula = 16 then pi is also equal to 3.14 so multiply 3.14 by 2 =6.28

47. Jake777

oh ok

48. samnatha

$6.28r=16$

49. Jake777

ok

50. samnatha

then r = 16 divided by 6.28 which is 2.54

51. samnatha

now you have r just fill out the formula

52. Jake777

oh i see now

53. samnatha

$4 \times \Pi \times 2.54^{2} = 81.07$

54. Jake777

ok cool

55. Jake777

56. samnatha

okay cool soz i couldn't helo with the last few ive no clue

57. samnatha

i dunno how to do the rest sorry
