Question

Complete the description of the figure that is generated by the rotation in three-dimensional space.

ВИ
A trapezold with two adjacent acute angles is rotated around a line containing the side adjacent to these
angles.
Sides BC and AD are neither perpendicular nor parallel to 1, so they form conical surfaces. Side CD is
perpendicular tol, so It forms a curved cylindrical surface. The figure formed by the rotation is a
composite of cones with a cylinder in between.

Answer 1

See bold type below.

Explanation:

Sides BC and AD are neither perpendicular nor parallel to l, so they form conical surfaces. Side CD is parallel to l, so It forms a curved cylindrical surface. The figure formed by the rotation is a composite of two cones with a cylinder in between.
