(weight of water is 62.4 pounds per cubic foot)
I set it up this way:
W = Integral (evaluated from 0 to 15) of (62.4)(pi)(64-y^2)(15-y)dy
I'm either incorrect in representing radius^2 as 64-y^2 which I derived from equation of an incremental disc of water having equation
x^2 + y^2 = 64 or in my limits of integration.
