## anonymous one year ago find the volume 2.5ft and 10 ft the options are 24.5ft 20.5 ft 48 ft 49 ft

• This Question is Open
1. Astrophysics

volume of what

2. anonymous

exactly @Astrophysics what are we finding the volume of

3. anonymous

the formula is v=pie r2 h

4. Astrophysics

Can you post the full problem

5. Astrophysics

Or take an image of it and post it here

6. Astrophysics

I noticed it's a cylinder

7. anonymous

yes please put the whole problem that will help us hep u

8. Astrophysics

What does 2.5 ft and 10 ft mean, is 2.5 ft the radius, is 10 ft the height?

9. anonymous

I think 2.5 is the radius and 10 is the height

10. anonymous

yes

11. anonymous

cool

12. anonymous

hold on i am trying to send it

13. Astrophysics

If so just use the formula they provided then $V = \pi r^2 h \implies \pi (2.5)^2(10)$

14. anonymous

you get 196.35 though?

15. Astrophysics

Yeah lets just wait for the problem

16. anonymous

k great

17. anonymous

18. anonymous

here it is

19. anonymous

I still got 196.35 what did u get @Astrophysics

20. anonymous

i did as well

21. Astrophysics

|dw:1439328678620:dw| so this is your problem either you're missing information or it's 62 pi ft^3

22. Astrophysics

23. anonymous

actually cubic feet sorry

24. Astrophysics

volume is ft^3

25. Astrophysics

Ok cool

26. anonymous

oj

27. anonymous

oh

28. Astrophysics

Are you sure that's the information..?

29. anonymous

yes

30. Astrophysics

Then that's it $V= \pi r^2 h = \pi (2.5)^2 (10) = 62.5 \pi~ ft^3$

31. anonymous

ok

32. anonymous

sorry I couldn't help :(

33. anonymous

thanks so much for trying

34. anonymous

u r so welcome

35. anonymous

i just figured it out its 49

36. anonymous

how is it 49

37. anonymous

did it explain?

38. anonymous

yes

39. Astrophysics

Mhm

40. Astrophysics

What did it say :o

41. anonymous

yeah I am wondering that to

42. anonymous

what did it say

43. anonymous

well i had to first do d=2r and then v=3.14(1.25)(10) came out to be 49

44. Astrophysics

What? That makes no sense

45. Astrophysics

we were using radius in the formula not diameter it shouldn't matter

46. anonymous

i know but that what my teacher told me

47. anonymous

that doesn't make sense I just solved it and got something total different than 49

48. Astrophysics

The formula is V = pi r^2 h...

49. anonymous

i thought it was rather confusing

50. anonymous

oh

51. Astrophysics

52. anonymous

yep i agree

53. anonymous

not to be rude but I agree with both of u

54. Astrophysics

I mean you can use diamater, but there is not need

55. anonymous

not being rude but sometimes teachers need to pay attention to their own way of stating a problem

56. anonymous

LOL TRUE DAT

57. anonymous

i just thought that i should let you all know what the answer was

58. anonymous

THNX FOR TELLING US

59. anonymous
