1- The base of a sand pile covers the region in the xy - plane that is bounded by the parabola(adsbygoogle = window.adsbygoogle || []).push({});

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.
