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

Option 1 - Triangle

Step-by-step explanation:

Given :  A cone is sliced so the cross section is parallel to its base.

To find : What is the shape of the cross section?

Solution :

When a cone is cut in such a way that the cross-section is perpendicular to the base and it passes through the vertex.

The shape of cross section formed is a triangle.

Refer the attached figure below.

The figure thus formed after cutting is in the shape of a triangle.

Therefore, Option 1 is correct.

step-by-step explanation:

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
