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_

Your basic equation for volume is \nV = Pi * R^2 * H        (this is the answer to part B)\nIf you put the values for radius and hight into that equation you have\nV = Pi * 4 * 6\nWe know Pi is 3.14159, so the equation solves\nV = 75.39822369\nI think you mistyped the 6 when aiming at the 9.\n\nYour constant is Pi.\n\nPutting the values for R=3 and H = 5 into that equation will get \nV = Pi * 3^2 * 5\nV = 3.14159 * 9 * 5\nV = 141.372

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!!

the symbol is called an angstrom. well 1 angstrom= 10^-8 cm =10^-10m.(10 to the power of -8cm) or one millionts of a cm.\n the answer to your question:\n\ndiameter=400 A\nthen radius =200 A\n length= 1500 A\n then volume= 2(pi).(200*10-8).(1500*-8) = 1.88*10-10 cm3\ntherefore mass= 0.24*(1.88*10-10)=0.4512*10-10 gm

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

Volume = (4/3) pi * radius^3\n\nRadius = Diameter / 2\n\nCristi has the right answer. Different people will use a comma in place of a decimal. It all depends on how you were taught. That's why it seems like the answer was a few orders of magnitude off when it was actually exactly right.\n\nTherefore, the answer is 113.097 cubic feet.

Volume = pi * r^2 * h\n\nr is 1/2 the radius of the drilled hole = (D'/2)\nh is equivalent to the diameter of the original cylinder = D

Given that the volume of the cylindrical can is 100 cm^2...\n\n100 = (pi)r^2h\n\ndivide both sides by (pi)r^2 to isolate h\n\nh = 100/(pi)r^2\n\nSo, if the radius is 2 cm...\n\nh = 100/((pi)*4) - r^2 = 2^2 = 4\n\nh = 7.96 cm, rounded to first two decimal places, using 3.14 as the value for pi.

Easy... fill the cone with some liquid.... then pour this liquid into a measuring cylinder and measure the amount of liquid... you'll get the volume of the cone.\n\nMathematically it is 1/3 the volume of Cylinder\nthat is 1/3(pie*r*r*h)

The method to finnd the volume of sphereis computed by The mathematician, Archimedes.\nThe formula for find the volume =4/3 pi  r cube\nie, pi = 3.14\n     r is the radius of the sphere.\nFor eg, r=1.2 m\n v =4/3 pi*(1.2*1.2*1.2) \n    =4/3*3.14*1728\n     =7.2346 cu.m\n     1 cu.m = 1000 litres\nV   =7.2346*1000\n       =7234.6\n\nDon't u understand.

Yes, the answer is h = 2r\n\nThis is a classic optimization problem. You want the minimum surface area(SA) for a cylindrical shaped tin for a fixed Volume(V)\n\n(1) SA = 2pi r^2 + 2pi r h\n\nV = pi r^2 h (for simplicity set V = 1)\n\nso (2)    h = 1/(pi r^2)\n\nSubstituting this value for h into (1) gives:\n\nSA = 2pi r^2 + 2/r\n\nd/dr SA = 4pi r - 2/r^2\n\nd/dr SA = 0 when 2/r^2 = 4pi r\n\nthat is: (3)   r = 1/(2 pi r^2)\n\nTo get the value of the ratio h/r divide equation (2) by equation (3), which yields a value of 2 to 1.\n\nh = 2r

i think n=6..\nyes this can be done..if you know the formula..\nof volume and surface arae of a hypersphere and also the form of gamma fucntion..\nhope you can do it yourself..i saw these two links and based on the formula given for volume and surface ares and the gamma fucntion expression its evident that n=6.\nHope you can figure it out yourself.\nvolume= pi^3/6 (radius =1 here)
