Math problem on the topic of circle calculation?

Hello,

I don't understand this task:

The solution:

Why is the thorn found twice on the diagonal?????

And why do you calculate d=2•7.62+2d????

Thanks for help!

I would argue like that

all symmetrical

If one of the four squares is now considered, the two sections on the diagonal together correspond exactly to a diameter of the mandrel.
So the diagonal of the square is missing a total of 2 mandrel diameters

Look at the right lower corner. Move them to the center along the diagonal shown.

You have room in the upper left and in the lower right corner. The distance from the puck to the corner is half a mandrel radius. Consequently, on the diagonal you have two puck diameters and two mandrel diameters

That’s a little complicated. As can be seen from the drawing, the radius of the mandrel is the distance from a corner point to the large circle.
