Unlike the implied warranty of merchantability, the implied warranty of fitness does not contain a requirement that the seller be a merchant with respect to the goods sold. It merely requires that the seller possess knowledge and expertise on which the buyer may rely.
The symbol used by mathematicians to represent the ratio of a circle's circumference to its diameter is the lowercase Greek letter Ï, sometimes spelled out as pi. In English, Ï is pronounced as pie (/paÉª/ , paÉª).
There are few other numbers as small as 360 that have so many different factors. This makes the degree a very nice unit to divide the circle into an equal number of parts. 120 degrees is 1/3 of a circle, 90 degrees is 1/4, and so on. So while a deeg, being 1/100th of a circle, may seem nice and round to us ten-fingered folks, it isn't so convenient for dividing a pie into thirds.
