Explanation Given: The length of a side of inscribed 24-sided polygon is, s = ( 8 − 24 − 8 2 ) r Here, r is the radius of the circle inscribing 24-sided polygon. The inner 24-sided polygon has perimeter approximately equal to the circumference of the circle. Calculation: Consider the figure of circle. Figure (1) The circumference of the circle is 2 π r . A circle is inscribed in the 24-sided polygon and another 24-sided polygon circumscribes the circle. Assume the sides of inner 24-sided polygon as s . The perimeter of inner 24-sided polygon is 24 × s . Circumference is the circle is equal to perimeter of inner 24-sided polygon. 2 π r = 24 × s π = 24 × s 2 r π = 12 × To determine (b) To find The value of π .
