What does 2.5 ft and 10 ft mean, is 2.5 ft the radius, is 10 ft the height?
anonymous
  • anonymous
I think 2.5 is the radius and 10 is the height
anonymous
  • anonymous
yes
anonymous
  • anonymous
cool
anonymous
  • anonymous
hold on i am trying to send it
Astrophysics
  • Astrophysics
If so just use the formula they provided then \[V = \pi r^2 h \implies \pi (2.5)^2(10)\]
anonymous

you get 196.35 though?

Yeah lets just wait for the problem

|dw:1439328678620:dw| so this is your problem either you're missing information or it's 62 pi ft^3
Astrophysics
  • Astrophysics
All your answers are in ft? Then that's not the volume
anonymous
  • anonymous
actually cubic feet sorry
Astrophysics
  • Astrophysics
volume is ft^3
Astrophysics
  • Astrophysics
Ok cool
anonymous
  • anonymous
oj
anonymous
  • anonymous
oh
Astrophysics
  • Astrophysics
Are you sure that's the information..?
anonymous
  • anonymous
yes
Astrophysics
  • Astrophysics
Then that's it \[V= \pi r^2 h = \pi (2.5)^2 (10) = 62.5 \pi~ ft^3\]
anonymous
  • anonymous
ok
anonymous
  • anonymous
sorry I couldn't help :(
anonymous

thanks so much for trying

u r so welcome

i just figured it out its 49
anonymous
  • anonymous
how is it 49
anonymous
  • anonymous
did it explain?
anonymous
  • anonymous
yes

Mhm
Astrophysics

What did it say :o
anonymous
  • anonymous
yeah I am wondering that to
anonymous
  • anonymous
what did it say
anonymous
  • anonymous
well i had to first do d=2r and then v=3.14(1.25)(10) came out to be 49
Astrophysics
  • Astrophysics
What? That makes no sense
Astrophysics
  • Astrophysics
we were using radius in the formula not diameter it shouldn't matter
anonymous
  • anonymous
i know but that what my teacher told me
anonymous
  • anonymous
that doesn't make sense I just solved it and got something total different than 49
Astrophysics
  • Astrophysics
The formula is V = pi r^2 h...
anonymous
  • anonymous
i thought it was rather confusing
anonymous
  • anonymous
oh
Astrophysics
  • Astrophysics
Your teacher is wrong
anonymous
  • anonymous
yep i agree
anonymous
  • anonymous
not to be rude but I agree with both of u
Astrophysics
  • Astrophysics
I mean you can use diamater, but there is not need
anonymous
  • anonymous
not being rude but sometimes teachers need to pay attention to their own way of stating a problem
anonymous
  • anonymous
LOL TRUE DAT
anonymous
  • anonymous
i just thought that i should let you all know what the answer was
anonymous
