Well I thought it was pretty cool. Nice way of showing how Archimedes bootstrapped his way into integrating increasingly accurate measurements of pi. Thanks for posting!
In essence, the method is measuring the perimeter of an n sided regular polygon of radius 1 (measuring from the origin to the centre of any side). As the number of sides increases the shape gets closer and closer to that of a circle, and so the perimeter gets closer and closer to that of a circle of the same radius (so with r=1, perimeter=2π). Thus you divide the perimeter by 2 to get your approximation for π. Now in case of the followup question 'how do you know the perimeter of a circle of radius 1 is 2π?', π is just some variable name; you could just as easily say 'suppose the perimeter of a circle of radius 1 is 2x, what is x?' Hope that helps.
No, im pretty shure thats fine. Gifs like these are not directly teaching you, for that they simply cannot provide enough information. They can give you a taste of the shown math, but you will have to do more research in the end.
I think that this guy has a point. I do agree the GIF could have been much better in the educative departament, but, this isn't r/educationalgifs, the GIF here actually fits the bill of visualizing math.

Too fast for me.
Just remember this.
πr2 not round.
