Special pig feed ingredients are required for your pig(s) diet because of their simple, monogastric stomach. Feeder Pigs require more concentrates (grain) and less roughage or fiber (hay) than cattle or sheep. This is especially true for young pig(s)s diet.
The distance half way around the circle is 3.14159265... a number known as Pi. Or draw a circle with a diameter (all the way across the circle) of 1. Then the circumference (all the way around the circle) is Pi. So Pi (the symbol is the Greek letter Ï) is: The ratio of the Circumference. to the Diameter. of a Circle.
Pi is a number that is approximately equal to 3.14. It is the number you get if you divide the circumference of any circle by its diameter. It's the same for all circles. You can approximate pi for yourself by taking some circular things like the tops of jars and CD's and frisbees and measuring their diameter and their circumference.
