Homework Help: Volume of apple juice

  1. Mar 30, 2014 #1
    A cylindrical container of height 1 m and diameter 0.5 m is partially filled with apple juice. When the container is lying on its side, the juice level at the deepest point is 37.5 cm (three eighths of a meter from the bottom of the cylinder is full). What is the liquid level after the container is raised up?

    What I thought of doing is that I found the intersection of the radius with the point where the juice is at its maximum. By using Pythagoras and trig functions, I could find the angle from which the radius goes from the center to the top of the juice.

    Now, I use the shell method, but instead of using 2pi, I used 4.1888.

    Integral of 4.188*y*(0.25) dy
    Then I added the triangular pyramid that was chopped off.

    Is my method correct? Could you please tell me how you would do this.

    What triangular pyramid? Sounds confused.
    Why not use the slice method ... sketch the cylinder end-on and divide the filled section into horizontal slices.
