how do i find the size of an object based on the size that I see it as?

Easy. Just use proportions. \nx = the height of the object\n12 / 28 or 3 /7 = 720 / x\ncross multiply\n3x = 5040\n x = 1680" = 560 yards

Pi by diameter\n( 22 / 7 ) X diameter

Looks to me like you are trying to figure out a "PERIMETER" rather than an "AREA".  If so, you need to ADD the lengths of all the sides together.  If you ARE looking for an area, it is simply Length x Width (for a rectangle or square), 1/2 the base x height (for a triangle), or Pi x radius squared (Pi is approximately =3.1415926) for a circle.  If the "shape" of the object you are trying to find the area of is irregular, then you must divide it up into these familiar shapes first, find EACH individual area, then add those areas together for the total area.

tricky question... you could probably get a fair approximation by looking at a computer model of the wonders and having the computer determine the surface area based on how much mesh is required to cover the model.\n\nIRL I would probably just take a model and see how much paint is required to cover the surface, that should give you a good estimate.

what is the diameter....? Just multiply the diameter times pi. (3.14)

A = lb = 98 in² (l = length and b = width, both in inches)\nSo b = 98/l\nWorking area W = (l - 8)(b - 4)\n= lb - 4l - 8b + 32\n= 98 - 4l - 8b + 32\n= 130 - 4l - 8b\n= 130 - 4l - 784/l\n\ndW/dl = - 4 + 784/l²\n= 0 for stationary points\nSo 4 = 784/l²\nie 4l² = 784\nThus l² = 196\nl = √196 (ignoring negative result)\n= 14 inches\nd²W/dl² = - 2 * 784/l³ < 0 when l = 14 so area is minimised when l = 14\n\nWhen l = 14 b = 7 (lb = 98)\nSo the dimensions to minimise paper used is 14 inches X 7 inches

circumference = pi * D\n\nwhere D is the diameter.

Find the weight the object (with a precision scales) and its volume (put it in water and look at the amount displaced).\n\nCalculate the density = weight (in gram) / volume (in milliliter)\n\nYou will find a number lying between 19.3 (density of pure gold) and 8.92 (density of pure copper). Say you found 18 gram/ml\n\nThen the amount of gold is   (18-8.92)/(19.3-8,92) = 87.5% gold

volume of cyllinder = area of circle times height\n\n= Pi x radius x radius  x height\n\nremember its just the same as finding the volume of any prism.\nfind the area of the shape of the end then multiply by its length!!

You need to change the size of the "slice" to change the size.  Make sure the slice layer is showing, increase the size of the relevant slice making sure it doesn't overlap a different slice.  \n\n-HTH

On the Toolbar- Go to View, Text Size, and then Select. (or the above works too.)

Take a rope ( that doesn't elongate/stretch easily), wind round both pulleys (just the way belt goes)and mark one end where it touches the other. Measure this and the size in inches is the size of the belt. As to whether 'A' or 'B' or 'C', it is based on cross-section. The smallest is 'A'. I hope I am understood.
