That was a fun problem to solve, I got 3+pi or around 6.14. Let's see if I'm right..
edit: i got it :D although i probably went through more steps and calculations than I needed
My intuition was correct.
Taking a shot 3+pi
Each of the 3 straight sections has length 1. Each of the 3 wrapped sections is 1/3rd of the circumference of a circle with diameter 1, or pi/3. So 3(1)+3(pi/3)=3+pi
1
I solved it in 10th grade in a exam
PziKimOJ7Yg&t=2m12s 2:12 2.pi.r = pi ? Should it be 2.pi ?
Edit : R is 1/2 unit
I would just find the circumference of the circle and then close YouTube
Well, I just missed the last circle 😂
Я минут за 20 решил, спросони. Только угол 120 * иначе нашёл - через достраивание внешнего треугольника и сумму углов ромба. Но так даже элегантнее.
I literally did this in my head in like two seconds after looking at the thumbnail lmfao
Took about 5 seconds to add it all together in my head.
6,14159
3+2π
I find these problems easy to solve. Just draw enough lines and put variables in between and you will have it.The hard part is to find the most simple and smartest way to do it without.
i did it yeah
3 + pi
А доказывать, что получаются три прямоугольника, кто будет?
But I solved this problem in a different way and my solution didn't match witj yours. I calculated the length of the circular arcs. As every arc have same length, I multiplied the length of one arc by 3.
Length of one circular arc=(2/3)×π
Total length of the arcs=3×(2/3)×π = 2π
The straight portions of the band have a total length of 3. So the total length of tje band becomes 3+2π.
The thing that confuses me is that the line that goes around the circles has to be a finite length, where as pi is infinite
