Anyone ready to answer some math question(s)?

OpenStudy (anonymous):

Give me a minute.

OpenStudy (marissalovescats):

Depends, what are they?

OpenStudy (anonymous):

Volume of a sphere.

OpenStudy (marissalovescats):

Oh yeah sure I can assist ya

OpenStudy (anonymous):

Okay, thanks. I'm pulling up the questions.

OpenStudy (marissalovescats):

Alrighty

OpenStudy (anonymous):

If a sphere has a radius 15 m, what is the volume of the hemisphere?

OpenStudy (anonymous):

Glad to see that you have a title called "Human Calculator".

OpenStudy (marissalovescats):

Alright so a hemisphere basically means half of a sphere. So to find the volume is really easy we do: |dw:1402625914189:dw| Where r is the radius. Then once we find the volume, we divide it by 2 because it's a hemisphere

OpenStudy (marissalovescats):

So what would we plug in for r?

OpenStudy (anonymous):

SO just put in 15 for r?

OpenStudy (marissalovescats):

Yup!

OpenStudy (anonymous):

Give me a minute to solve.

OpenStudy (marissalovescats):

And you can leave it in terms of pi or you don't have to

OpenStudy (anonymous):

We're solving for V right? Just to be sure.

OpenStudy (marissalovescats):

Yes r=15 is the only thing you need to know to solve this

OpenStudy (anonymous):

4500(pi)

OpenStudy (anonymous):

4500(pi)m^3

OpenStudy (marissalovescats):

Oops sorry you're right I had the answer without pi

OpenStudy (marissalovescats):

But yes 4500pi m^3

OpenStudy (marissalovescats):

Great Job :)

OpenStudy (anonymous):

Thanks, you don't mind me asking some few questions?

OpenStudy (marissalovescats):

Sure go ahead

I'm going to post a new question not here. I'll tag you.
