Question

Transcribed Image Text:In this question we are going to find approximate values of T using geometrical constructions.
You should perform the constructions using computer software and include them with your solution.
7.
(a)
On the same circle, inscribe and circumscribe squares.
(b) Assuming the circle has a radius of 1, find the areas of the circle and the two squares,
and then compare them to create an inequality for r: that is, you should be able to show
that is between two numbers. Comment on how good this approximation is.
(c)
Using the fact that tan = v2-1 (but don't bother proving that fact), repeat parts a)
and b) for inscribed/circumscribed octagons.
Archimedes (of bathtub fame) used polygons inside and outside circles to approximate TT
(d)
over 2000 years ago, although he compared perimeters instead of areas. Research his
method to find out what size polygon he used (that is, how many sides) and his final
approximation for 7.
