What number is pi divisible by?
In fact π is not equal to the ratio of any two numbers, which makes it an irrational number. A really good approximation, better than 1 part in 10 million, is: 355/113 = 3.1415929……Approximation.

What what equals pi?
approximately 3.14
Succinctly, pi—which is written as the Greek letter for p, or π—is the ratio of the circumference of any circle to the diameter of that circle. Regardless of the circle’s size, this ratio will always equal pi. In decimal form, the value of pi is approximately 3.14.
How do you get pi?
In some ways Pi (π) is a really straightforward number – calculating Pi simply involves taking any circle and dividing its circumference by its diameter.
What fraction is the closest to pi?
22/7
We all know that 22/7 is a very good approximation to pi. But this well-known fraction is is actually 1/791 larger than a slightly less-well-known but much more mysterious rational approximation for pi: . The fraction 355/113 is incredibly close to pi, within a third of a millionth of the exact value.
Is pi divided by 2 rational?
Number π2 cannot be expressed as a quotient of integers, so it is an irrational number.
What are the first 15 digits of Pi?
For those who don’t know, Pi is defined as the ratio of a circle’s circumference to its diameter. The first 15 digits of the never-ending number are: 3.14159265358979.
What is 1 radian, in terms of Pi?
Degrees to radians in terms of pi. The angle α in radians is equal to the angle α in degrees times pi constant divided by 180 degrees: α(radians) = (α(degrees) / 180°) × π. Convert 30 degrees angle to radians in terms of pi: α(radians) = (α(degrees) / 180°) × π = (30° / 180°) × π. = (1/6) × π = π/6 rad = 0.166667π rad.
What is 1 divided by cosine?
Sine, Cosine and Tangent. The three main functions in trigonometry are Sine, Cosine and Tangent. They are just the length of one side divided by another. For a right triangle with an angle θ : Sine Function:
