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 the ratio of a circle's circumference to it's diameter. It's useful for working out various things about a circle. For example, Where R is the radius of a circle and D is the Diameter (D = 2R), piRSquared will give you the area and piD gives the circumference.
