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.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
