Question

what shape is this cross - section? a. circle b. rectangle c. triangle d. trapezoid

Explanation:

A trapezoid has one pair of parallel sides. When a plane cuts a cylinder at an angle (not parallel to the base or perpendicular to the axis in a non - circular - creating way as in this case), the cross - section formed has one pair of parallel sides (the two opposite sides of the cross - section). A circle would be formed if the cut is parallel to the base of the cylinder. A rectangle is formed when the cut is perpendicular to the base (and along the axis). A triangle cannot be formed by cutting a cylinder in a single - plane cut.

Answer:

D. Trapezoid
