6. rachelagain

Thank you :)

7. EnteringStacis

no problem ;)

8. sasogeek

@EnteringStacis how did you arrive at your answers?

9. EnteringStacis

by using the formula 4 * pi * radius^2

10. EnteringStacis

And yes, I know you are going to get mad at me for not explaining or showing work... but idk, she is my friend, she knows how to do them, she just need then done.

11. rachelagain

Yeah, they told us about the formula.

12. rachelagain

In fact, I will check them right now.

13. sasogeek

4*pi*r^2 ?

14. sasogeek

if that's the formula u used... i'm sorry to inform u but that's wrong :) u might want to check again

15. rachelagain

4/3pir^2

16. sasogeek

it's $$\large \frac{4}{3} \pi r^3$$

17. sasogeek

if that's not what you have, confirm it from wikipedia :) http://en.wikipedia.org/wiki/Sphere#Volume_of_a_sphere just in case.

18. rachelagain

Oh, Stacis, I used the formula 4/3pir^3 and got 3052.08
