In this question, we have three circular pencils that each has a diameter of one centimeter.
00:06
They'll be held together by an elastic band, and we want to know what is the length of the length.
00:12
Here is stretch.
00:14
So we can represent then that we have these three here.
00:20
All of them have the same diameter of one.
00:23
So these all have one.
00:27
Then we have the elastic band.
00:30
And scroll it, let me put in, use another code.
00:34
And it's going over here, through, like this.
00:45
So there are some parts that is like, they are touching the circumference, right? like there's parts here that is actually touching the pencil, but there are all the parts here, three of them.
00:58
They all between.
01:01
So in this case, what we have is that this is the center of these two...
