Is it asking for the Approximate or exact?
Ohhh! It shows the PI sign at the end so it's asking for exact. :)

jabez177 · Answer

$$V=\frac{ 4 }{ 3 }\pi r ^{3}$$

jabez177 · Answer

We just plug it in. :)

jabez177 · Answer

r = 6

rebeccaxhawaii · Answer

Plug r=6 into what jabez gave you

jabez177 · Answer

$$6\times6\times6=6^{3}$$

jabez177 · Answer

What is $$6^{3}$$

jabez177 · Answer

Or in smaller terms, what is 6 x 6 x 6 :)

216

jabez177 · Answer

Right! 
So now we don't multiply the PI, just the 4/3

jabez177 · Answer

Or let's just to 4 for now.
What is 216 x 4?

volleyballlover55 · Answer

864

jabez177 · Answer

Now divide that by 3 because we still have the 3 left over. :)

try and do pi * 6^3 *4 /3

jabez177 · Answer

Noooo!!!
You do not multiply by PI!! 
They want the Exact volume, not Approximate. :)
