i stink at math but how do you determine the volume of sphere?
Thank you, that is the trouble with using the same letter to stand for more than one thing. It gets very confusing. Now it makes sense and seems to be coming back from my physics days.

I already posted that earlier. Volume = (4/3) X pi X radius cubed (r^3)

I'm not even sure if you need that because the question would normally have "Use 3.14 for pi" or something like that ... It has that all the time.
Hmmm ...
I was wondering how did you convert the 212.27387 (m*m*m) to litres xD sorry I'm bad with units
..
so how exactly do we get the answer?
I used 999 kg/m^3 as my water density. Since density is related to temperature, according to the chart on wikipedia, 1000 kg/m^3 would be less than 0 degrees C. Your water would be frozen. *lulz*
http://en.wikipedia.org/wiki/Density#Density_of_water
By using that different density, my answer was 212570.
scratch my question figured it out lols.
So is that the answer? 212570?
Check out this page for Math formular. The previous answer is not correct!

I prefer you guys don't give out answer as I posted the formula
Thanks for the formula! I just happen to be doing pre calc homework now-
I can't figure out what is X?
In your explanation it says that the r=8.6, but in the problem the diameter is 8.6, so wouldn't that make r=4.3?

I had that same question too!
Sorry my mistake, I have it in my draft x but I changed it. I will explain the formula when I have time. It's calculus. I corrected a mistake too.
I saw it-thanks for the update. how about the radius formula on your page? It says 8.6=r
I was wondering where it came from, thank you tons. I'm in calculus now, and this kind of relates to what we're doing, so that's neat.
yeah, like I said above, I made a mistake and just corrected it. Thanks for pointing out.
