Why wouldn't the integral for the cone problem be from 0 to 8 instead of 2 to 10
Since 0 was placed at the top of the cone, and the water level is 2 feet from the top (the water drains downward), we integrate from 2 to 10 because we only add up disks where there is water, and there is no water from 0 to 2.
