$V_{\text{sphere}} = \frac{4\pi r^3}{3}$

@Hero I got 904.7808

3. bumblebee3 Group Title

What does this symbol mean? ð

4. Hero Group Title

pi I suppose.

I got the same volume formula and my volume on the windows calculator was $$904.7786842338604526772412943845$$ using its estimation of $$pi$$. The exact answer is $$288\ \pi$$.

6. Hero Group Title

288 pi = 904.7808

And so I agree with @Hero again. Maybe it was just an issue with the computer code. I don't see why anyone would substitute a symbol for $$\pi$$ if that's what that means.

And the units are $$[\text{in.}^2]$$

9. theEric Group Title

So, that looks right..

10. Hero Group Title

cubic is in^3

Pfft, $$[\text{in}^3]$$, you're right again.
