Outside of the technical issues, there is a concern about turning foodâcorn in the U.S.âinto fuel. Partially driven by an 8-percent rise in corn orders from ethanol plants, corn prices doubled in the last six months of 2010 and are expected to continue rising. There are benefits to ethanol, of course. It has a higher octane rating, so it supports a higher compression ratio and more aggressive ignition timing. Like its cousin methanol, with its high octane and clean burn, ethanol makes a good racing fuel. NASCAR, a politically astute organization, is running E85 this season.
I agree with Diane that with this meaning of the word cylinder it has 3 faces, 2 edges and no vertices. There is however a technical meaning of the word cylinder that results in a different answer.
A cylindrical segment, sometimes also called a truncated cylinder, is the solid cut from a circular cylinder by two (or more) planes.If there are two cutting planes, one perpendicular to the axis of the cylinder and the other titled with respect to it, the resulting solid is known as a cylindrical wedge.he volume of the cylindrical section can be obtained instantly by noting that two such sections can be fitted together to form a cylinder of radius and height, so the volume of the original wedge is half that of the cylinder of height, i.e., (1).
