How do you calculate the number of cubic feet in a cylinder?

Volume = pi*r^2*h\n\nWhere pi = 3.14.159...\nr = raduis of cylinder in feet\nh = height of cylinder in feet

0.0145 diameter means Pi x 0.0145 square inches in cross section = 0.0455 square inches. Multiply this by 1000 ft (convert feet to inches by using 12000inches) gives you 546.6 cubic inches for the entire piece. The density of aluminum is\n2.70 grams per cubic centimeter, so you convert 546.6 cubic inches to cubic centimeters by multiplying by 16.387 giving a total of 8,957 grams altogether.

You can do this with some math.  I'm assuming 12 feet is the diameter.  So the radius would be half that, or 6 feet.  2.5 feet (30 inches) is the height.\n\nThe volume of a cylinder is the area of the circle, times the height.\n\nV = pi r^2 h\n\nSo the volume is 3.14159 x 36 x 2.5\nThis is approximately 282.743339 cubic feet.\n\nOne cubic foot holds 7.48051945 US gallons, so you multiply 282.74 x 7.48 to get around 2,115 gallons.\n\nIncidentally, a gallon of water weighs 8.34 lbs, so you are talking about 17,639 lbs or nearly 9 tons of water!!!  Be sure the sides and the base are well constructed.

The curved surface area of the cylinder would be made up of the circumference times the height.  Figure the circumference then divide the surface area by that to get the height.  it would probably be best to convert M2 into cm2 first.  100 cm=1M so 1 sq m would be 100 x 100 or 10,000sq cm x 4m2 equals 40000 cm2.  The C would be 2(pi)r  which is 2 x 3.14 x 70 = 439.6 cm.  Divide 40,000 by 439.6 = 90.99 cm for the height. volume would be (pi)r2h or 3.14 x 4900 x 90.99 = 1399972 cu cm

Volume = pi * r^2 * h\n\nwhere\nr is the radius\nand\nh is the height\n\nFor example:\nr = 0.9m\nh = 1.2m\nvolume = 3.14159 * 0.9 * 0.9 * 1.2 = 3.0536 cubic metres or 3053.6 litres\n\n_

Volume = Area x height\nArea = r x r x pi\npi is approximated by the fraction 22/7\nTherefore Volume of cylinder = 4 x4 x 22/7 x7 = 352 units^3

Radius of the cylinder = 225 mm / 2 = 112.5 mm\n\nThe length is given in metres, so work in metres \n112.5 mm = 0.1125 m \n\nCross sectional area of cylinder = pi * r^2 = 0.03976078... sq m\n\nVolume = length * cross sectional area \n= 1 m * 0.03976078 sq m = 0.03976078 cu m\n1 cu m = 1000 litres\ntherefore volume = 39.8 litres to 3 s f

to figure out cubic meters, you multiply length times width times height.  so, 82746 in x 4 in x 2 in = 659,808 inches cubed\n\nthen you convert cubic inches into cubic feet by multiplying by 0 . 0005787, and then to cubic meters by multiplying by 0 . 0283168 \n\n(the other way to do this would be to convert the length measurements from feet into meters and then to multiply the new length width and height values together.  to convert from feet to meters, multipy by .3048)

this is 250 liters, that is 250 cubic meters.\n\nVolume of the cylinder is (area of the base)*height.\nAs the base is a circle, its area is (squared radius)*Pi.\n\nIf you assume Pi almost equal to 22/7, you can take its inverse, 7/22, and multiply by 10: you get 70/22. Take this value in meters as the height and 5 meters as the radius of the base.

The long way to do this is much simpler:\n\n1) convert everything into inches and re-write the problem.\n2) do the easy math\n3) see how many times 12 goes into your new answer (that'll be the number of feet in your answer)\n4) then add on the remainder (that'll be the number of feet in your answer)

This is not tricky at all. The volume is 1-1/2 cylinders of "height" 50,000 meters and radius 4 meters.\n\nThe formula for the volume of a cylinder is\n\nV = pi * r^2 * h
70150
so you have to find the surface area of a cylinder that is 35diameter and 40 ft tall. or \n((3.14)17.5^2)40)

If the tank is a cylinder, the Volume is πr²h.  If you get the volume in cubic feet, multiply by 7.5 to get gallons.

The volume unit would be a cubic unit as it is 3-dimensional. It would depend on the unit of measure in the equation.\n\nThe calculation for volume of a cylinder is (pi) * radius^2 [squared] * height.\n\nOr out in English "Pi times the radius squared times the height"

If you type "x  cubic inches in cubic centimeters" into google, an answer will appear insteaad of websites. Or You could mltiply the amount in cubic inches by 16.387064.
