The easiest way I found to do this one was to work on the area of the end circle. First, focus on the upper half of the end circle. Use calculus to calculate the area from y=0 to y=2 where x=SQRT(16-y^2). Using the substitution rule and solving the integral we get an area of 14.933 ft^2. Add this to the bottom half of the circle which is 25.133 ft^2 and we get a total of 40.066 ft^2. Now multiply by the length of the tank (25 ft) and the answer is 1001.65 ft^3.

v=lwh so 4*25*6
