Ahorizontal cylindrical tank 8.00 ft in diameter is half full of oil (60.0 ib/ft3). find the force on one end

Assuming h as the height of the cylindrical tank

Explanation:

Assuming that the height is we can find the volume of the cylindrical tank, then:

The diameter is 8.00 ft then the total volume of the tank is:

But the tank is half full of oil, then we need half of the volume. For that reason the volume of oil is:

We know the density of the oil , with this we can fing the mass of oil that we have because:

then

Then the mass of oil that we have is:

Note that with the value of h we have the mass in correct units.

Finally to find the force we now that then we just need to multiply the mass by the gravity.

the answer is 100. i just did this lesson and got a 100% on it. : )
