OpenStudy (confluxepic):

Ok.

OpenStudy (confluxepic):

\[3000=\frac{ 4 }{ 3 }\pi(r)^{3}\]

OpenStudy (anonymous):

That is the equation for the first one?

OpenStudy (confluxepic):

Yes.

OpenStudy (anonymous):

What else?

OpenStudy (confluxepic):

\[9000=4\pi(r)^{3}\]

OpenStudy (confluxepic):

\[\frac{ 9000 }{ 4\pi }=r^{3}\]

OpenStudy (anonymous):

Anything else?

OpenStudy (confluxepic):

\[r^{3} \approx 716.197\]

OpenStudy (anonymous):

Is that it?

OpenStudy (confluxepic):

\[r \approx 8.95\]

OpenStudy (anonymous):

How did you get that?

OpenStudy (confluxepic):

I cubed rooted it.

OpenStudy (anonymous):

ok awesome part 2?

OpenStudy (confluxepic):

\[SA=4\pi(r)^{2}\]

OpenStudy (confluxepic):

\[SA=4\pi(8.95)^{2}\]

OpenStudy (anonymous):

4pi*80.1025

OpenStudy (confluxepic):

\[SA=4\pi(80.04)\]

OpenStudy (confluxepic):

That is if you don't round the radius to 8.95.

OpenStudy (anonymous):

Is that it?

OpenStudy (anonymous):

@confluxepic

OpenStudy (confluxepic):

\[SA=320.19\pi\]

OpenStudy (confluxepic):

\[SA=1005.9\]

OpenStudy (anonymous):

For part 1 or part 2?

OpenStudy (confluxepic):

Part 2.`

OpenStudy (anonymous):

Wait so far i have this for part 2: 4pi(r)^2 4pi(8.95)^2 4pi(80.04)

OpenStudy (confluxepic):

Yes.

OpenStudy (anonymous):

What do i type after?

OpenStudy (confluxepic):

I said it a bit earlier.

OpenStudy (anonymous):

4pi(r)^2 4pi(8.95)^2 4pi(80.04) What else?

OpenStudy (anonymous):

So do i add those 2 after those 3 lines i already have?

OpenStudy (confluxepic):

Yes.

OpenStudy (anonymous):

Oh ok great, Only 1 question left then im done @confluxepic You've saved my life lol.

OpenStudy (confluxepic):

I know.

OpenStudy (anonymous):
