Find the volume of a cylinder with a radius of 3 cm and a height of 7 cm.

OpenStudy (anonymous):

Do you happen to know the equation for the volume of a cylinder?

OpenStudy (anonymous):

9π cm3 21π cm3 42π cm3 63π cm3 Dont know..

OpenStudy (anonymous):

Do you have access to google...

OpenStudy (anonymous):

Not at the moment..

OpenStudy (anonymous):

well it's V = pi(r^2 * h)

OpenStudy (anonymous):

Which is? lol Dont have a calculator

OpenStudy (anonymous):

So you know your height and radius. All you have to do is plug it in to the equation.

OpenStudy (anonymous):

Well you can do this without a calculator.. What is \[3^{2}\]?

OpenStudy (anonymous):

32? lol

OpenStudy (anonymous):

that was not my answer..

OpenStudy (anonymous):

You gotta be kidding me. What is 3 times 3?

OpenStudy (anonymous):

9

OpenStudy (anonymous):

Now what is 9 times 7?

OpenStudy (anonymous):

63

OpenStudy (anonymous):

Those answers don't look right...

OpenStudy (anonymous):

we didn't even multiply by pi yet.

OpenStudy (anonymous):

Well what now?

OpenStudy (anonymous):

Oh nevermind. Apparently my OS lagged and I couldn't see the PI sign. The answer is 63pi.

OpenStudy (anonymous):

Thats no an option..

OpenStudy (anonymous):

not*

OpenStudy (anonymous):

It's the last option buddy.

OpenStudy (anonymous):

Oh yeah lol.. stupid me

OpenStudy (anonymous):

What is the volume of a cereal box that is 2 inches thick, 12 inches high and 10 inches wide?

OpenStudy (anonymous):

What shape is a cereal box?

OpenStudy (anonymous):

OpenStudy (anonymous):

When have you ever seen a cereal box that is a ball? or even a pyramid? A cereal BOX.

OpenStudy (anonymous):

Ive seen some weird cereal boxes lol

OpenStudy (anonymous):

I'd love to live in your area.

OpenStudy (anonymous):

So how do I find the answer?

OpenStudy (anonymous):

We're dealing with a rectangular prism here buddy. The length, width and height gives it away.

OpenStudy (anonymous):

To find the volume, multiply the length, the width and the height.

OpenStudy (anonymous):

I don't know how to do that..

OpenStudy (anonymous):

Okay let's break it down. I'll give you a cookie when we're done.

OpenStudy (anonymous):

Yay! I love cookies

OpenStudy (anonymous):

Alright! Awesome. Now you must answer this correctly or I break your cookie in half.

OpenStudy (anonymous):

what is 12 times 2?

OpenStudy (anonymous):

24

OpenStudy (anonymous):

what is 24 times 10?

OpenStudy (anonymous):

240

OpenStudy (anonymous):

Wow. Great job. That is your answer.

OpenStudy (anonymous):

Send me your address so i can mail the cookie.

OpenStudy (anonymous):

Yay. Just send it virtually

OpenStudy (anonymous):

Uhh i don't know how to do that. No computer.

OpenStudy (anonymous):

Nvm. I'll just imagine eating a nice warm chocolate cookie

OpenStudy (anonymous):

Cool.

OpenStudy (anonymous):
