My 1st grader's homework had a problem about the number of sides on a circle. I have a BS in Math and never thought about it, my initial thought was 1. Turns out there are multiple correct answers:
2 sides: Outside and inside
1 side: There is only one line
0 sides: A circle has no sides.
∞ (infinite) sides: Each point in a circle would be a separate side (yes, way too egghead for 1st grade)
TOPICS: Miscellaneous; Science
KEYWORDS: circle; farside; infinity; sides

Each of the "correct" answers is using a different definition of "side" to come to the conclusion.
If you can't articulate the definition of "side," the question of how many sides is not really mathematical.

In two dimensions there is no top or bottom.

On paper, a top side and a bottom side too!

I checked the internet and Twitter has banned all answers.

If a side is how many boundaries that are contiguous and parallel, I would say infinite.

If the circle is in a plane, like a coin, then there are 2 sides, heads and tails.

There is no far side of the Moon. Matter of fact it’s all far.

I suspect that the teacher is fishing for the answer, an infinite number of sides. A circle can be thought of as the limit of a sequence of multi-sided polygons, each with more sides than the last.

Yes, always one far side and also one close side. But does it not have a top side and a bottom side or is the up side down? For that matter, what about the right side and the left side? Is there an independent side?
You know, even as a kid people have tried to get me to see the man in the moon, but all I have ever seen is a bunch of impact critters.

Or infinity, because a circle can be considered to have an infinite number of infinitesimal sides and corners. You’re probably right, though. Infinity is not a concept expected to be in the wheelhouse of 1st graders, but zero is.

"In two dimensions there is no top or bottom" ================================
In the field of topology a circle isn't limited to the geometric concept.

A circle has 2 sides. It has an inside and an outside!

"How many sides on a circle?
BIDEN: Two sides
TRUMP: Infinite Sides
MODERATOR: Mr. Biden is correct.
To: where's_the_Outrage?
Infinite... in the limit.

I would have said infinite.
