There are very few real life examples of nonagons. The only examples that I can think of are a few coins.

Conic sections have several disadvantages, including the complexity of their equations compared to simpler geometric shapes, such as circles or rectangles. Additionally, conic sections can be difficult to visualize and manipulate, especially for individuals who are not familiar with their properties and characteristics. Finally, conic sections may not always accurately represent real-world objects or phenomena, making them less practical for certain applications compared to other geometric shapes.

Roads are an example of intersecting lines in the real world.
I need hardly explain where you encounter circles.Ellipses are encountered when you cut a cylindrical object (e.g., a sausage) at an angle. Parabolas are the approximate paths taken by objects thrown into the air (when air resistance is insignificant). Hyperbolas: I may be wrong, but it would seem that these are less common in real life. ALL of the conic sections can be seen when you shine a flashlight onto a level floor (or some other plane), since the light cone is, precisely, a cone.
Scales or balances.
