Cubic feet is a measurement of volume. Volume for a cylinder is the surface area of the top circle multiplied by the length. So [(pi)(radius)2] x [height]= volume
The volume of a cylinder is a product of its length, the square of its radius, and the irrational number pi. The radius is half the diameter, so that the volume of this cylinder in cubic feet is (4)(0.5)2(pi) = about 3.14 cubic feet. There are 27 cubic feet per cubic yard, so that this equals 3.14/27 = about 0.12 cubic yard, where the last digit is depressed because it may not be significant -- there is only a single significant digit given for the dimensions of the cylinder.
The radius of the cylinder is half of the diameter, so the radius is 1 foot. The volume of a cylinder is calculated using the formula V = πr^2h, where r is the radius and h is the height. Plugging in the values, the volume of the cylinder is V = π(1)^2(12) = 12π cubic feet.
Use the formula for the volume of a cylinder: V = radius2 x Pi x height5 ft2 x 3.142 x 6 ft = about 471.3 cubic feet
The volume of a cylinder = height * pi * radius^2. So, Volume = 2*pi*0.5^2 = pi/2 cubic feet.
To determine how many 40 lb bags of topsoil are needed to cover 12 cubic yards, first convert cubic yards to cubic feet. There are 27 cubic feet in a cubic yard, so 12 cubic yards equals 324 cubic feet. Assuming a 40 lb bag covers about 1.5 cubic feet, you would need approximately 216 bags (324 cubic feet ÷ 1.5 cubic feet per bag = 216).
The gallon is a unit of volume, so we must assume that you have calculated the volume in units of cubic inches, cubic feet, cubic centimeters, or some other cubic unit. If so, use Google to do the conversion. If, for example, the volume of the cylinder is 100 cubic inches, just type 100 cubic inches in gallons in the Google search box.
http://wiki.answers.com/Q/What_is_the_volume_in_cubic_feet_of_a_cylinder_with_a_diameter_of_18_inches_and_height_of_4_feet 12*12*12 = 1728 (this is the amount of cubic inches in one square foot) Since we are using inches in our question, but requesting the answer to be in feet, we will use 1728 inches cubed as our equivelant of a cubic foot. The other conversion will be to change 4 feet to 48 inches. H*(base area) = V of a cylinder Base = area of a circle = pi*r squared With pi being = 3.14, the formula for your solution is: D= 18 (so r= 9) pi= 3.14 4 feet= 48 inches ((9*9)*pi)*48= 12208.32 which we divide by the equivelant of a cubic foot (1728) to arrive at our solution of 7.065 cubic feet. The volume in cubic feet of a cylinder with a diameter of 18 inches and height of 4 feet is 7.065 cubic feet (using 3.14 as pi).
There are 3 feet in 1 yard, so 33 = 27 cubic feet in a cubic yard. Therefore divide cft by 27.
2.13 ton of what? Ton is a unit of mass, and cubic feet is volume. So you would need to know the density of the material, in order to determine volume from mass.
3 ft = 1 yard so 3*3*3 = 27 cubic feet = 1 cubic yard and so 144 cubic feet = 144/27 = 5.33... cubic yards.
1 cubic metre = 35.3 cu feet so 28 cubic metres = 988.8 cubic feet.
To convert cubic feet to cubic yards, you need to divide the number of cubic feet by 27 since there are 27 cubic feet in a cubic yard. So, to convert cubic feet to cubic yards, divide the number of cubic feet by 27.
