Ethanolâs Impact on Livestock Profitability. The economic environment for the livestock and poultry sector changed dramatically, starting in 2006. In a few months, despite a record 2005 U.S. corn crop, feed costs more than doubled and feed price variability increased sharply.
Hi, A cylinder has 3 faces - 2 circle ones and a rectangle (if you take the top and bottom off a tin can then cut the cylinder part on the seam and flatten it out you would get a rectangle). It has 2 edges and no vertices (no corners). Diane. Hi Stacy,
A cylinder whose cross section is an ellipse, parabola, or hyperbola is called an elliptic cylinder, parabolic cylinder, or hyperbolic cylinder respectively. An elliptic cylinder with the half-axes a and b for the surface ellipse and the height h.An elliptic cylinder is a quadric surface, with the following equation in Cartesian coordinates : This equation is for an elliptic cylinder, a generalization of the ordinary, circular cylinder (a = b).here d is the diameter. For a given volume, the closed cylinder with the smallest surface area has h = 2r. Equivalently, for a given surface area, the closed cylinder with the largest volume has h = 2r, i.e. the cylinder fits snugly in a cube (height = diameter).
