But corn alone will not keep pigs growing and healthy. Corn must be supplemented with Pig(s) food(s) vitamins to keep pigs healthy.
Pi is the ratio of a circle's circumference to it's diameter. The resulting number is the reason there cannot be a perfect circle. It's value is approximately 3.142 which, rounded up to the nearest whole number, would be four. It would not be three, as that would be rounding down.
By definition, pi is the ratio of the circumference of a circle to its diameter. Pi is always the same number, no matter which circle you use to compute it. For the sake of usefulness people often need to approximate pi. For many purposes you can use 3.14159, which is really pretty good, but if you want a better approximation you can use a computer to get it. Here's pi to many more digits: 3.14159265358979323846. The area of a circle is pi times the square of the length of the radius, or pi r squared: The modern symbol for pi [] was first used in our modern sense in 1706 by William Jones, who wrote: Pi (rather than some other Greek letter like Alpha or Omega) was chosen as the letter to represent the number 3.141592...
