    It is much easier if you just replace r with a number. 3 for example. Then its just 2 root x 6 +3+3 and then divide by 2, square, and then X 3,141592654 =164,79
    And 6x6=36 - 3x3x3,141592654 = 7,725666. 164,79-7,72 and then /7,72 =20,3308.

    • @lagomoof
      @lagomoof 6 месяцев назад

      It doesn't matter how big the diagram is, the ratio stays the same. If I take my sandwich and use a magical expansion ray on it, the ratio of bread to slice of beef ought to remain the same, right? You wouldn't expect the bread to increase and not the beef, or vice versa. If that happened the sandwich wouldn't look like an expanded version of how it started.
      But coming back to mathematical reality (such as it is), the ratio staying the same is proven by there being an r² in both the numerator and denominator which cancel out (see 2:17). If the ratio was dependent on r somehow, something would prevent that from being possible and there would be an r left over somewhere.
