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 has 2 flat surfaces and 1 curved surface. In differential geometry, a cylinder is defined more broadly as any ruled surface spanned by a one-parameter family of pa â¦ rallel lines.s such it can have any number of flat surfaces but need not have any at all. A cylinder whose cross section is an ellipse, parabola, or hyperbola is called an elliptic cylinder, parabolic cylinder, or hyperbolic cylinder respectively; these have no flat surfaces. 7 people found this useful.
