In geometry, a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints are on the circle. The diameters are the longest chords of the circle. The word "diameter" derives from Greek διάμετρος (diametros), "diagonal of a circle", from δια- (dia-), "across, through" + μέτρον (metron), "a measure"). In more modern usage, the length of a diameter is also called the diameter. In this sense one speaks of the diameter rather than a diameter, because all diameters of a circle have the same length, this being twice the radius. For a convex shape in the plane, the diameter is defined to be the largest distance that can be formed between two opposite parallel lines tangent to its boundary, and the width is defined to be the smallest such distance. For a curve of constant width such as the Reuleaux triangle, the width and diameter are the same because all such pairs of parallel tangent lines have the same distance. See also Tangent lines to circles. The diameter of a connected graph is the distance between the two vertices which are furthest from each other. The distance between two vertices a and b is the length of the shortest path connecting them (for the length of a path, see Graph theory). From Wikipedia under the

I am building a 10'x12' deck that will be attached to my house and have three footers. I will be using 6x6 posts. I know the depth that I need to go for my footers, but am wondering what diameter they should be to accommodate my post size. Thanks! Asked by MPK23 - Fri May 22 15:26:58 2009 - - 3 Answers - 0 Comments A. Drill your holes 12" and if you are using Sonotubes, go with 10". Hope this helps. EDIT: Maybe KTB ought to learn how to read. 12" diameter holes, 10" diameter sonotubes. The question asked wasn't about depth, it was diameter. But I guess since he is so busy owning a plumbing, electrical, masonry, HVAC, gardening, international banking company, he doesn't have the time or capacity to do any of them well. Answered by woodtick314 - Fri May 22 15:31:10 2009 Would Earth's diameter be less if the current liquid mantle turned solid all the way to the core? Q. If I understand correctly, liquid state matter occupies more space compared to solid matter. So, if the Earth's liquid mantle (or lava) were to somehow solidify and be compacted all the way to the iron core, would the overall earth's diameter decrease? If so, would we all be heavier because the effects of gravity would be more due to us being closer to the Earth's core? If the Earth's diameter does decrease, what would the new estimate be? And how much heavier (weight - not mass) would we be as a result? The answers received so far don't really answer the question. Please help!!! Asked by Pearly Shells - Tue Dec 30 15:12:46 2008 - - 12 Answers - 1 Comments A. i think you answered the question yourself! the solid would be more dense and take up less space, so the diameter would probably decrease. and yes, as distance decreases the force increases, so we would weigh more, but our mass would be the same. Answered by snowwflake20 - Tue Dec 30 15:17:15 2008 does the diameter in contact lenses really matter?
Q. I was planning on purchasing some colored contacts but come to find out my diameter is a 14.2 and the contacts i want have a diameter of 14.0. Does it matter if its a difference by 0.2? Asked by nattyboo - Thu Jan 1 21:51:07 2009 - - 6 Answers - 0 Comments A. Since the colored contact has a smaller diameter than your prescription, the colored part will not completely cover your iris and you will be able to see a ring around your iris that shows the natural color of your eye. Also they may not fit quite right. If the contact is not the same as your prescription it won't fit your eye right, also if the contacts need to have a prescription strength, the company may not sell it to you. Contact companies are required to have the person's prescription faxed, emailed or confirmed by an optometrist. They are not legally allowed to sell some one contacts that are not correct for their eyes. But if they are nonprescription strength, you will probably be fine, they just won't cover your iris completely… [cont.] Answered by butterfly kisses - Thu Jan 1 21:59:11 2009 From Yahoo Answer Search: "diameter" |
