Write a C++ program that computes a pair of estimates of , using a sequence of inscribed and circumscribed regular polygons. Halt after no more than 30 steps, or when the difference between the perimeters of the circumscribed and inscribed polygons is less than a tolerance of =10. Your output should have three columns, for the number of sides, perimeter of inscribed polygon, and perimeter of circumscribed polygon. For the last two columns, display 14 digits after the decimal point. Your program and the output should appear in a Scientific Workplace document. Comment on your results. Warning: You may find that the answers differ from your expectations.
