"an open tank has the shape of a right circular cone. the tank is 6 feet across the top and 5 feet high. how much work is done in emptying the tank by pumping the water over the top edge? note: the density of water is 62.4 lbs per cubic foot."

The amount of workdone by in emptying the tank by pumping the water over the top edge is

Explanation:

Given that the tank is 6 feet across the top and 5 feet high.

Using the similar triangles.

5r = 3y

Thus; each disc is a circle with area

A =

The weight of each disc is ;

= 62.4 ×

=

The distance pumped is 5-y

Thus; the workdone in pumping the tank by pumping the water over the top edge is :

The amount of workdone by in emptying the tank by pumping the water over the top edge is

i would say the answer is food.

hope this !
