Volume of cylinder = area of base * height.\nSince the base is a circle, that part is Pi *r^2\nSo we have Pi * r^2 * height --> \n3.14 * 12^2 * 21 = ?\n\nVolume of square prism = area of base * height\nSince the base is a square, that part is side^2\nSo we have 12 * 12 * 21 = ? \n\nSubtract the results for your final answer.

use the formula pi*r^2*h\nwhere pi=1.34\n r=radius (in inches)\n  h=height of cylinder (inches)

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 of the sphere is 4/3*pi*r^3\n\nThe volume of the cylinder is pi*r^2*h\n\nSince the cylinder's h is the same as 2r, then the volume becomes pi*r^2*2r which is the same as 2*pi*r^3.\n\nThe fraction of the space taken up by the sphere is the same as:\n\n4/3*pi*r^3\n-------------\n2*pi*r^3\n\nwhich is the same as:\n\n4/3\n----\n2\n\nwhich reduces down to 2/3

The volume of a cylinder is the area of the base (a circle) times\nthe height of the cylinder.  The pipe represents a cylinder.\nThe area of a circle is PI times the radius squared (PI X r^2)\n\ndiameter of pipe = 24 inches implies the radius = 12 inches implies radius = 1 foot.  Length of pipe is height of cylinder\nnew value of PI = 3.1416 exactly (?)\n\nVol of Cylinder = Area of Base                      X Height of Cylinder \nVol of Cylinder = Area of Circle                     X Height of Cylinder \nVol                   = PI(3.1416) X radius(1 ft.)^2 X height(8 ft.)\nVol                   = (3.1416 sq.ft.)                     X height(8 ft.)\nVolume            =  25.1328 cu.ft. exactly

graduated cylinder or callibrated pipette are the answers to the test questions in my classroom.  And in scientific situations, volume is measured in liters/litres- except when measured in cc's (cubic centimenters)

one can find the volume of a three-dimensional object. an oval (ellipse) only has an area. a three-dimensional oval will be an ellipsoid. \n\nthe volume formula is :(4/3)*(pi)*(r1)*(r2)*(r3)\nwhere \nwhere r1 = radius 1, r2 = radius 2, r3 = radius 3 \nthe radii of the three dimensions

The definition of the volume of an object is just how much space it occupies.\nIf you're looking for the formula for volume, then \nV = Pi(r^2)h, where r is the radius and h is the height.

Volume is L * W * H ... if the Volumen is 1000^3 and it's a cube, then L, W and H all = 1000cm\n\nDuh.

Cylinder = PI r^2 x 6 r = 6PI r^3\nBalls = 4/3 x PI r^3 x 3 = 4 PI r^3\nratio = 4 PI r^3 / 6 PI r^3 = 4/6\n\nRatio = 2/3 of the space is used by the balls.

There's a formula for volumes of gasses:\n\nPV = nRT.\n\nIf I remember right, P = pressure, V = volume, n = number of moles, T = temperature, and R = molar density, or something molar that is specific to the gas.

use the formulas your given\nto find the volume of the cylinder\nthen pretend the semi hemi on  the top is a sphere find the volume and multiply by 1/2\n\nadd two totals to find volume

dia = diameter, right?\n\nok...\n\nV = pi * r²h\n\nV = pi * 0.5m² * 1.2m\n\nV = pi * 0.3m\n\nV = around 0.942478m³.\n\nSo a cylinder with diameter 500 mm and length 1200mm gives us 942.478 litres of fuel.\n\nThat is though, if we ignore the thickness...\n\nEDIT\n\nWhoops, I mistook the diameter to be the radius. The correct answer is the above divided by 4, or about 235.62 litres.

Use Heron's formula to find the area of the base: 6 times the square root of 5.  Then multiply that by the height.\n\nThe volume is 30 times the square root of 5.

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"
