Question

a cone is sliced so the cross section is parallel to its base. what is the shape of the cross section?
trapezoid
circle
triangle
semicircle

Explanation:

When a cone is sliced parallel to its base, the cross - section has the same shape as the base. The base of a cone is a circle. A trapezoid is a quadrilateral with one pair of parallel sides and is not related to the cross - section of a cone parallel to its base. A triangle is the cross - section when a cone is sliced through its vertex and perpendicular to its base. A semicircle is half of a circle and does not form when slicing a cone parallel to its base.

Answer:

circle
