Question

1. Find the volume V of the described solid S.

The base of S is an elliptical region with boundary curve 9x2 + 16y2 = 144. Cross-sections perpendicular to the x-axis are isosceles right triangles with hypotenuse in the base.

2. Find the volume V of the described solid S.

The base of S is the triangular region with vertices (0, 0), (2, 0), and (0, 2). Cross-sections perpendicular to the y-axis are equilateral triangles.

3. Find the volume V of the described solid S.

The base of S is the triangular region with vertices (0, 0), (5, 0), and (0, 5). Cross-sections perpendicular to the x?axis are squares.
