A circular swimming pool has a diameter of 22 ft, the sides are 5 ft high, and the depth of the water is 4 ft. How much work is required to pump all of the water over the side? (Use the fact that water weighs 62.5 lb/ft^3.)
(a) Show how to approximate the required work by a Riemann sum. Give your answer using the form below. (If you need to enter -infinity or infinity, type -INFINITY or INFINITY.)
(b)Express the work as an integral and evaluate it.
The Attempt at a Solution
I've found everything in the riemann sum equation minus the "E". What would this be?
One I find that, I should be able to setup the integral and solve it.
