(I Kings 7, 23) The same verse can be prime in II Chronicles 4, 2. It occurs in a list of specifications for the great synagogue of Solomon, built nearly 950 BC and its interest here is that it gives ? = 3. not a rattling accurate economic value of human body and not even in truth accurate in its day, for the Egyptian and Mesopotamian values of 25/8 = 3.125 and ?10 = 3.162 flip been traced to oft earlier dates: though in defence of Solomons craftsmen it should be noted that the item being exposit seems to have been a very large brass casting, where a high gradation of geometrical precision is neither manageable nor necessary. There atomi c number 18 some interpretations of this which lead to a much better value. The detail that the ratio of the circumference to the diameter of a circle is uniform has been known for so long that it is quite a untraceable. The soonest values of ? including the Biblical value of 3, were almost certainly found by measurement. In the Egyptian Rhind Papyrus, which is dated about 1650 BC, at that prepare is good evidence for 4 × (8/9)2 = 3.

16 as a value for ?. The first theoretical calculation seems to have been carried out by Archimedes of Syracuse (287-212 BC). He obtained the approximation 223/71 < ? < 22/7. beforehand giving an indication ! of his proof, notice that very massive edification involved in the use of inequalities here. Archimedes knew, what so some(prenominal) flock to this day do not, that ? does not equal 22/7, and made no claim to have discovered the comminuted value. If we postulate his best estimate as the average of his two move we obtain 3.1418, an error of about 0.0002. Here is Archimedes argument. grab by a circle of radius 1, in which we...If you want to get a full essay, order it on our website: BestEssayCheap.com
