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).
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 pi added to pi over two?
(pi^2+2pi)/2pi
Pie plus pie equals what?
If you mean the number pi, pi + pi is usually written as 2pi.
Is 2Pi r the same as Pi r squared?
No. 2Pi r is equal to Pi d, though.
What is the diameter of a circle that is equal to pi?
If you mean the diameter of a circle with area pi, then the diameter is 2. If you mean the diameter of a circle with circumference pi, then the diameter is 2. If you mean the diameter of a circle with diameter pi, then the diameter is pi. If you mean the diameter of a circle with radius pi, then the diameter is 2pi.
Is 2pi rational?
NO. pi is an irrational number, therefore, 2pi is also an irrational number/
What is the circumference of a circle when the area is 36 pi?
To convert area into circumference, take the two formulas for circles--circumference and area: C=2pi*r A=pi*r^2 Now, isolate the common variable (r) in the second equation. r=sqrt(A/pi) Now you can substitute this in for "r" in the first equation to find circumference C=2pi*sqrt(A/pi) C=2pi*sqrt(36pi/pi) pi cancels out C=2pi*sqrt(36) C=2pi*6 C=12pi
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 plus pi?
pi+pi is 6.28. all that you have to do is add up the numbers.-fromama fromamzez.webs.com
What is the radius of the circle if the circumference of the circle is 13 pi cm?
C = 2 pi r (divide by 2pi to both sides) C/2pi = r (substitute 13 pi cm for C) r = (13 pi cm)/(2 pi) = (13/2)(pi/pi) cm = 6.5 cm
