A 16 foot tall wall is next to a cylindrical tank

that has a radius of 4 feet and is 8 feet tall.

The tank is full of a liquid that has a density

of 60 pounds per cubic foot.



Represent the amount of WORK done to

lift (pump) the top 3 feet of liquid to the top

of the wall as an integral.

(use "pi" for PI=3.14159)


Work = $\displaystyle {\int_{{\text{a}}}^{{\text{b}}}}$ Preview Question 6 Part 1 of 4   dx

a =

b =

Then evaluate the integral. Work = $\displaystyle {f}\infty{t}\cdot{p}{o}{u}{n}{d}{s}$
