Alright,
formula for a sphere is (4
r^3)3
4*pi*6^3=2714.34/3
904.78
Now you can do this 2 ways. First is that a cone is 1/3 of a sphere with the same radius so just take 904.78 and multiply it by 1/3 and then by 2 to get 2/3 of it or do this.
cone~ (6^2*pi*10)/3
376.99
and subtract
<span>904.78-376.99=527.79
</span>
<span>527.79^3 greater. Check my math. I could be wrong.</span>
