What is the formula for finding the volume of a cylinder

Volume of a right circular cylinder of radius r and height h is
V=PI*(r^2)*h
Figure out which is the radius and which is the height, then plug in the formula above. Result is in cm^3

volume is calculated by finding the area multiplied by the length or height . That is Pi X radius squared X length
example --tube 6"dia 12"long what is the volume?
Example 3.1417 X radius 3" Squared =3.1417X9sq " = 28.2740sq" X length 12" =338.688 cubic"
If you want the volume of an engine cylinder , it is the same formula and the length is the stroke of the piston ( distance from TDC to BDC )

V = (pi)(r square)(h) V= Volume (the amount we need to calculate)
pi = 3.14...
r = radius of cylinder (remember this is half that of the circumference)
h = height of cylinder

To make it easier for you below are the figures for the Cylinder.
Radius= 11.5 inches
Height = 17 inches.
Now use the formula above to calculate it.

For the Jelly Bean its,
Radius = 0.25 inches
Height = 0.5
Use the same formula above for jelly bean as well.


Once you have both figures, divide Volume of Jar by Volume of Jelly e.g. VolumeofJar/VolumeofJelly

AND VOILA, you have the amount of jelly beans in a jar (Round the figure out)

Cheers!

Each specific solid (shape) that has some regularity has a formula which can be used to calculate its volume. If it has no regularity the calculation will be more complicated.
For a right rectangular prism with dimensions L, W, H the volume is L*W*H. For a right circular cylinder with radius r and height H, the volume is Pi*r^2*H.
Once you know the formula, it is an easy matter to use the calculator to evaluate the volume.

There isn't a single formula for solids of different shapes. For a right solid with a rectangular base - volume is base area x height Similarly for cylinder with a circular base - volume = base area x height (base area in this case is Pi x radius2). For a sphere - volume = 4/3 x Pi x radius3

You're finding the volume of a cylinder. This site gives the formula and some examples. You need to do some conversion when you start solving this because some of the dimensions are in meters and others in mm. Just remember that there are 1000 mm in one meter.

Using the formula for a cylinder's volume: v = pi * r * r * h, and the data h = 730 m, r = 100 mm = 0.1 m,

v = 3.14 ^ 0.1 * 0.1 * 700. The result will be in cubic meters, and I'll let you do the math.

When you have to deal with problems of this sort, you usually are given recipes or mathematical formulas which you apply to find the result. It so happens that for the volumes of cylinders, the formula to use is
Volume = Area of the base times the height=Ab*h
If the cylinder is circular, then the area of the base is that of a disk, Ab=PI*r^2`where r is the radius.
In your case, you are given the diameter (twice the radius) and the height.
Volume =PI*h*(6.2/2)^2, the unit being cm^2

To type in the value of PI, press [2nd] [^] (the latter is key under CLEAR, and above the division sign.
To raise a number to power 2 (to square it), use the key marked x with a superscript 2, or x with a raised 2.
After you have typed in all necessary ingredients in the formula, press the [ENTER] key and the calculator will give you the result.

Now, it is your turn to do some mathematics.

Calculate the volume of one 55 gallon drum by using this formula
22/7 X Radius squared X hight of cylinder = Volume of large vessel.
22/7 X 48" (Squared) X 24" = Volume in cu in

100.57 cu ft in large pool = 752.315 US gals.
110% of 50 gals = 60.50 gals
752.315 divided by 60.5 = 12.43 drums
Draw to scale the large poola nd then draw to scale the smaller drums and see if 13 drums fit.

Figure the volume of the entire cylinder, minus the volume of the core. Multiply the weight per cubic inch times the number of cubic inches of poly. To figure the length, you will have an equasion longer than your arm, since each wrap is slightly longer than the previous wrap.
