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).
The circumference of a circle relates to one of the most important mathematical constants in all of mathematics. This constant, pi, is represented by the Greek letter Ï. The numerical value of Ï is 3.14159 26535 89793 ... (see A000796). Pi is defined as the ratio of a circle's circumference C to its diameter d : Or, equivalently, as the ratio of the circumference to twice the radius.
