CAN PI EQUAl 2?

Question

CAN PI EQUAL 2?

Answer 1

no

Answer 2

If you use a 1.7xxxx or 11/7 based numbering system, then yes. Example: 11/7 = 1. 22/7 = 2.
This is like binary, or hexadecimal, where 5 in binary = 101. 5 does not equal 101, its just that there are only 2 numbers allowed in binary, 0, and 1. As for hexadecimal, the number 12 is B, since it goes 0 1 2 3 4 5 6 7 8 9 A B C D E F 10 11 ....

i hope this helps. -_-

Answer 3

Pi is the circumference of a circle divided by its radius. That ratio is so exact and occurs often that it was given a special character: pi. Most people use 22/7 in calculations, but it only repeats the 3.14 part. The rest of 22/7 does not match the number for pi; however, it is the closest to a fraction that people have arrived at.

Answer 4

Depends how you define pi.

The mathematical definition of pi is usually so rigorous that it always has the same value of 3.1415926etc.

However, it you use it as the ratio, in a circle, of the circumference over the diameter (or over twice the radius) and it you use a non-plane surface, then it is possible to have any value you want (hence the reason for the strict definition mentioned above).

For example, place yourself at the north pole on a sphere with a radius equal to Earths (we'll just imagine Earth being a perfect sphere for this thought experiment).

You place the dry point of the compass exactly at the pole and draw a small circle of radius r. Over such a small distance, the ratio of the circumference over 2*r is 3.1415926etc. That is why we say, over very short distances, Earth's surface can be considered flat.

Let's get a huge compass and draw a circle with a radius r of exactly 1800 nautical miles. The circle we will draw will correspond to the line of latitude 60 degrees (North).
Remember that I'm considering the Earth to be a perfect sphere, in practice, you may have to use a slightly different radius.

The circumference of the circle of latitude 60N can easily be measured: it is 10,800 nautical miles.

Divide the circumference by 2*r = 10,800 / 3,600 = 3.0 exactly.

Get an even bigger compass, use a radius of 5400 nautical miles. You will then draw the equator. The length of the equator is 21,600 nautical miles (used to be the basis of the definition of the nautical mile before the SI took over).

21,600 / (2*5400) = 2

And, of course, you can continue to make the radius bigger and draw circles of southern latitudes (circumference smaller than the equator) to get even smaller values of our newly defined "pi", all the way down to 0 when we use a radius of 10,800 nautical miles.

Answer 5

NO! Pi equals 3.14 and that is all of it I know but it goes on for what seems like forever.

Answer 6

Actually, Pi is equal to:

And so on...

Answer 7

absolutely, pi can equal anything your little heart desires. just divide pi by pi and in your case multiply by two.

the answer is 2

in all other cases it is usually equal to 3.141592653587

Answer 8

Pi by itself cannot equal 2. But if you subtract a number, multiply, or divide, it could.

pi*x=2
x=2/pi

pi/x=2
pi=2x
pi/2=x

pi-x=2
pi=2+x
pi-2=x

Answer 9

Pi is a fixed number it always stays the same
3.14159265......and so on

Answer 10

Never

Answer 11

Possibly.... if the most fundamental rules of the universe change.
