You can put this solution on YOUR website!
You are looking at a cylinder. See http://library.thinkquest.org/20991/geo/solids.html
The volume of such a cylinder is given by V+=+pi%2Ar%5E2%2Ah
where r is the radius and h is the height.
You are given a diameter of 12. So the radius is 12/2 = 6.
The height is 10
V+=+pi%2A6%5E2%2A10
V+=+pi%2A36%2A10
V+=+pi%2A+360
As an estimate, V%5Best%5D+=+3.14%2A360
V%5Best%5D=+1130.40 cubic whateverUnitsTheygaveYou
