178: Hexagonal Densepack

What is the best way to find the perimeter of the rounded hexagonal shape, i.e., the length of the belt that would wrap around the six wheels?

r = 1


  1. I get more bummed the closer that number comes to 180.

    This one is great. Love that the prompt isn't "calculate the area" (not conducive to argument) but "what's the best way."

  2. Wait, I'm confused. It says "the best way to find the area of the rounded hexagonal shape," but then says "length of the belt." Isn't length the perimeter?

  3. Funny, 294 people looked at that. I fixed it to say perimeter.
