Ah, yes sorry about that!

igreen · Answer

No, that's incorrect.

igreen · Answer

It wants the exact Volume, which is in terms of pi.

igreen · Answer

$\sf V = \dfrac{4}{3} \pi r^3$

Take pi out:

$\sf V = \dfrac{4}{3}r^3$

$\sf V = \dfrac{4}{3}(6.5)^3$

Simplify

Oh. Would it be C then? (second answer.) I kinda doubt it would be A...

igreen · Answer

Yep, that's what I got.

igreen · Answer

All of them have pi next to it, right?
