CAN PI EQUAl 2?
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 (No
