Sprinkle sesame seeds and find the approximate value of pi.Draw a square and a circle inscribed in it, and sprinkle sesame seeds on it at random.The approximate value of pi can be obtained from the ratio of the number of sesame seeds in the square to the number of sesame seeds in the circle.Specifically, the approximate value of pi can be obtained by the following formula.Approximate value of pi = (number of sesame seeds in a circle) ÷ (number of sesame seeds in a square) x 4Lets explain the reason mathematically.However, this app is experimenting for a quarter of a yen.
