@EnteringStacis how did you arrive at your answers?

anonymous · Answer

by using the formula 4 * pi * radius^2

anonymous · Answer

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.

anonymous · Answer

Yeah, they told us about the formula.

anonymous · Answer

In fact, I will check them right now.

sasogeek · Answer

4*pi*r^2 ?

sasogeek · Answer

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

anonymous · Answer

4/3pir^2

sasogeek · Answer

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

sasogeek · Answer

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

anonymous · Answer

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