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,
So this also obeys Euler's formula and we have: |V| - |E| + |F| = 1 - 1 + 2 = 2. So a sphere can be said to have 1 vertex, 1 edge and 2 faces. Many texts and people would have said a sphere has no edges, no vertices and 1 face. It all depends on how the terms are defined.
