Step-by-step explanation:
multiply every side by 5 since it's a square each side is equal!
no solution
it's just 41
1024pi/3
to find the volume of a sphere you use the equation 4/3*pi*r^3
4/3*pi*8^3
4/3*pi*512
2048/3 pi
This is the volume of the whole sphere but we only need half so we can just divide by 2.
(2048/3 pi)/2
1024/3 pi
