Answer:

Cone

Step-by-step explanation:

I took the test and got it right :)

The triangle is rotated about the y-axis then a cone will be formed.

It is given that the triangle is rotated about the y-axis as shown in the picture.

It is required to find what three-dimensional polyhedral would be formed.

What is the triangle?

The triangle can be defined as a three-sided polygon in geometry and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

We have an image of a right triangle centered at the origin in the picture, if we rotate it about the y-axis we will get a cone because the side which is at the y-axis will be fixed and the base of the triangle will move about the y-axis which will make a circular shape similarly the other side(hypotenuse) will also rotate about the y-axis which will create an outer surface for the cone.

Thus, the triangle is rotated about the y-axis then a cone will be formed.
