Pi is a greek letter (π) that, in geometry, is used to indicate the constant ratio of any circle's circumference to its diameter. It is an irrational number, meaning that it cannot be expressed as a fraction of two integers. In practice, this means you can never evaluate the circumference of a circle exactly. The value of pi, rounded to 5 decimal places, is 3.14159. Modern sumpercomputers have calculated pi to over a trilliion (1,000,000,000,000) decimal places. However, from a practical point of view, no one ever needs more than 8 or 10. In fact, at just 39 decimal places, the approximation of pi is sufficient to calculate the circumference of the entire observable universe, and be off by no more than the width of a single hydrogen atom.

What is the phase shift for sin 2pi plus pi?
Assuming you mean that the pi is not within the sin(2pi), its a vertical shift of +pi
What is the circumference of a circle to give 1 meter square?
area of a circle = pi * radius² = 1 radius = √(1/pi) circumference = 2pi * radius = 2pi * √(1/pi) = 3.5449077
What is the area of a circle with a circumference of 410 meters?
Circumference = 2pi*r 410 = 2pi*r r = 205/pi A = pi*r^2 A = pi*(205/pi)^2 A = 205^2/pi metres A = 42 025/pi metres
What is the radius if the circumference is 16 feet?
Circumference = 2*pi*raduis 16 = 2*pi*r divide both sides by 2pi 16/2pi = r 8/pi = radius
What is pi over 12 on a radian circle?
pi/12 = (pi/12)/(2pi) = 1/24 of a circle ( = 15 degrees).
