11 Consider a cylindrical tank that has a height of 11 m and a radius of 4 m Recall that if the tank is full of water then S 16mpg 15 y dy equals the work required to pump all the water out 0 of the tank through an outflow pipe that is 15 m above the bottom of the tank Revise this work integral for the following scenario Do not evaluate the integrals The work required to empty the tank through an outflow pipe at the top of the tank If D y is the distance a horizontal slice must be lifted what is D y when the outflow pipe is at the top of the tank D y
