WebPi, in mathematics, is a constant which is the ratio of the circumference of a circle to its diameter. It is an irrational number often approximated to 3.14159. It is denoted by the Greek letter 'π' and is spelled as 'pie'. Sometimes, to ease the calculation, the value of pi is used in the form of a fraction as 22/7. WebThe circumference is pi times the diameter if it were opened up and straightened out to a line segment. The circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle. If a circle has a diameter of 4, its circumference is 3.14*4=12.56. If you know the radius, the diameter is twice as large.
