OpenStudy (narissa):

@k_lynn

OpenStudy (anonymous):

You cant post a question again to bump it

OpenStudy (mahmood786123):

One seccond

OpenStudy (narissa):

huh? its a different question

OpenStudy (k_lynn):

Since we want to approximate, we multiply by pi. The formula is \[\frac{ 1 }{ 3 }\Pi r ^{2}H\]r is the radius, h is height.

OpenStudy (anonymous):

It says "I need help with volumes" I saw it pop to the top twice before my bump button appeared.

OpenStudy (k_lynn):

So when we plug in 4 for r and 9 for h, we have this \[\frac{ 1 }{ 3 }\Pi4^{2}9\]

OpenStudy (mahmood786123):

150.8cm³

OpenStudy (narissa):

is it 432

OpenStudy (narissa):

i posted a new question

OpenStudy (anonymous):

Not to be annoying, I just wanted to let you know you should be careful because that is against the rules.

OpenStudy (k_lynn):

No, not quite. When you plug it into a calculator, divide 1/3 then multiply by 3.14, multiply by 4^2and multiply by 9.

OpenStudy (narissa):

what is?

OpenStudy (mahmood786123):

This is your answer

OpenStudy (anonymous):

Taking down a question and putting it back up again so it goes to the top.

OpenStudy (narissa):

OpenStudy (narissa):

OpenStudy (mahmood786123):

I gave you the answer to the old one

OpenStudy (mahmood786123):

Didnt realize you posted a new question

OpenStudy (narissa):

im talking to that person that is saying im reposting the same question

OpenStudy (mahmood786123):

W

OpenStudy (mahmood786123):

Ok

OpenStudy (narissa):

now i got 150.72

OpenStudy (k_lynn):

We have to multiply this. \[\frac{ 1 }{ 3 }\times3.14\times4^{2}\times9\]

OpenStudy (anonymous):

Just even if you're not, use different text to start it, it can be mistaken for rule breaking.

OpenStudy (k_lynn):

yep, you got it @narissa :)

OpenStudy (narissa):

thank u

OpenStudy (k_lynn):

Sure, no problem.

OpenStudy (anonymous):

Just be careful, even if it's not the same, people may think you are reposting.
