A rectangular tank that is 4 meters long, 2 meters wide and 3 meters deep is filled with a rubbing alcohol that has density 786 kilograms per cubic meter. In each part below, assume that the tank is initially full, and that gravity is 9.8 meters per second squared. A) How much work is done pumping all of the liquid out over the top of the tank?

B) How much work is done pumping all of the liquid out of a spout 1 meters above the top of the tank?

C) How much work is done pumping two-thirds of the liquid out over the top of the tank?

D)How much work is done pumping two-thirds of the liquid out of a spout 1 meters above the top of the tank?

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,

is there more to this question?

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
