The volume of a sphere is given by:
V+=+%284%2F3%29%28pi%29r%5E3
If the radius is 3.00 inches, then r = 3, so...
V+=+%284%2F3%29%28pi%29%283%29%5E3
V+=+%284%2F3%29%28pi%2927
V+=+36%28pi%29 If you use %28pi%29+=+3.14 as an approximation, then...
V+=+36%283.14%29
V+=+113.04Cu.ins.
If the sphere is filled with liquid weighing 1.50 lbs/cu.in, then the weight will be:
%28113.04%29%281.5%29+=+169.56lbs.
