A solid has a base in the form of an ellipse with major axis 10 and minor axis 8. Find its volume if every section perpendicular to the major axis is an isosceles right triangle with one leg in the plane of the base. Ans. 640/3 cubic units The base of a solid is the segment of the parabola y² = 12x cut off by the latus rectum. A section of the solid perpendicular to the axis of the parabola is a square. Find its volume. Ans. 216 cubic units The base of a solid is the first-quadrant area bounded by the line 4x + 5y = 20 and the coordinate axes. Find its volume if every plane section perpendicular to the x axis is a semicircle. Ans. 1077/3 cubic units The base of a solid is the circle x² + y² = 16x, and every plane section perpendicular to the x axis is a rectangle whose height is twice the distance of the plane of the section from the origin. Find its volume.
