1. A rectangle 10 feet wide and 8 feet deep is submerged vertically in water with its upper
edge lying in the surface. Find the force on one side of the surface using integration. The
specific weight of water is 62.4 pound per cubic foot.

2. Find the length of the curve 3y = (x² + 1)ī from x = 0 to x = 3.
3. Find the surface area generated when the arc given by y = 2/15 – x; 0 <x < 15 is
revolved about the x-axis.
4. Find the area enclosed by the polar curve r = 2 - soso.
5. The external fuel tank for a space shuttle has a shape that may be obtained by revolving
the region under the curve,
