Homework Help: Sand pile vector physics

  1. Oct 19, 2008 #1
    1- The base of a sand pile covers the region in the xy - plane that is bounded by the parabola
    x(power of 2) + y = 6 and the line y = x. The height of the sand above the point (x,y) is x(power of 2).
    a) set up the volume of sand as
    i) a double integral
    ii) a triple integral

    b) then, find the volume by using any methods you have found from a)i or a)ii

    2- let D be the smaller cap cut from a solid ball a radius 2 units by a plane 1 unit from the center of the sphere.
    a) Set up the volume of D as an iterated triple integral in
    i) cylindrical coordinate
    ii) spherical coordinate

    b) then, find the volume by using one of two triple integrals you have found from a)i or a)ii.
