Question

If a triangular cross-section with coordinates at (1, 1), (1, 4), and (3, 1) is rotated about the line

x=1, what will be the resulting three-dimensional object?

A) Cone

B) Cylinder

C) Sphere

D) Pyramid

Answer 1

When a triangular cross-section is rotated about a line, it creates a cone.

Step-by-step explanation:

When a triangle is rotated about a line, it creates a three-dimensional object called a Cone. In this case, the triangular cross-section will create a cone when rotated about the line x=1.
