.
Volume of any sphere is:
%284%2F3%29%28pi%29r%5E3
where
pi is 3.14
r is the radius
.
%284%2F3%29%28pi%29r%5E3+=+320
%284%2F3%29%283.14%29r%5E3+=+320
4%283.14%29r%5E3+=+960
%283.14%29r%5E3+=+240
r%5E3+=+76.433
r+=+4.24 meters

Hi,
Using the formula for the Volume of a Sphere:
V+=+%284%2F3%29+pi%2A+r%5E3
.
%283%2F4%29320+=+pi%2Ar%5E3
%28240%2Fpi%29+=+r%5E3+
Show cube root of %28240%2Fpi%29
