Associate's degree programs in computer information technology are generally offered at community colleges or technical schools. Students are taught to install and upgrade software and hardware, develop computer networks, and to assess the information and computer needs of an organization.
According to Math Open Reference, pi is a mathematical constant obtained by dividing the circumference of any circle by its diameter. Pi is about 22/7 or 3.142. However, no one knows its exact value.
The number Ï is a mathematical constant, the ratio of a circle 's circumference to its diameter, commonly approximated as 3.14159. It has been represented by the Greek letter  Ï  since the mid-18th century, though it is also sometimes spelled out as  pi  (/paÉª/).ome people use a different value, Ï = 6.283185... = 2 Ï, arguing that Ï, as the number of radians in one turn or as the ratio of a circle's circumference to its radius rather than its diameter, is more natural than Ï and simplifies many formulas.
