## anonymous 5 years ago how do i find the volume of a sphere?

1. anonymous

$4/3\pi r ^{3}$

2. anonymous

sorry, $4/(3\pi r ^{3})$

3. anonymous

wow, I'm having trouble with this; $4/3 \times \pi r ^{3}$

4. anonymous

they should have a fraction option in the equation builder...

5. anonymous

it's 4/3 times pi times the radius squared.

6. anonymous

i mean cubed sorry

7. anonymous

okay so if the radius is 3 than its 4/3 (3pi3^3)

8. anonymous

No, it's $4/3(\pi3^{3})$
