What is the value of pi out to 30 digits past the decimal point?

Pi (л) represents the ratio of the circumference of a circle to its diameter (л = circumference/diameter). Some calculations in which this value is used include: the area of a circle (A=лr² ), the volume of a cylinder (V=лr² h), and the volume of a cone (V=1/3лr²h). Pi is an "irrational number," meaning it extends into infinity and does not have repeating sequences of digits.

Because it's impossible to write out infinite digits, pi is written in an abbreviated form. When doing calculations by hand, pi is generally rounded to 3.14. When working with a calculator, the value for pi is rounded to the number of digits that will fit on the display screen, which is often 12. Rounded to 30 digits past the decimal point, pi equals 3.141592653589793238462643383279.
