Young Azerbaijani researcher Shamistan Alizadeh proposed an important formula for more accurate calculation of the Pi number in mathematics. According to his hypothesis, the roughest form of a circle is an equilateral triangle.

If we want to calculate the length of the circle more accurately, it is more optimal to approach the circle from the inside, starting from an equilateral triangle drawn inside the circle and increasing the number of its sides. In this case, the length of the circle is calculated more accurately as n- approaches positive infinity in the equilateral n-angle drawn inside the circle. In this case, as the length of the circle becomes more accurate, the value of Pi becomes more accurate. With the formula proved by Shamistan Alizade by this method, it is possible to calculate the pi number 3.16… value obtained by Babylonian and Egyptian scientists and 3.14…. values obtained with the latest technology in modern times and more accurate values.
