Corn is an excellent energy feed, and is ideal for finishing feeder pigs because it is high in digestible carbohydrates, low in fiber, and is very tasty feed for pigs to pigs! 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.
The circumference of a circle relates to one of the most important mathematical constants in all of mathematics. This constant, pi, is represented by the Greek letter Ï. The numerical value of Ï is 3.14159 26535 89793 ... (see A000796). Pi is defined as the ratio of a circle's circumference C to its diameter d : Or, equivalently, as the ratio of the circumference to twice the radius.
