The formula is 4/3 x pi x r3

r is the radius

pi is approximately 3.14 So if your sphere's radius is 2 inches, the calculation looks like this:

2 x 2 x 2 x 3.14 x (4 / 3) = 33.5103216 This means that your sphere's volume is 33.5 cubic inches.

What is the volume of a siphon tube?

The volume of a siphon tube would depend on its specific dimensions, such as length and diameter. To calculate the volume, you would use the formula for the volume of a cylinder, which is V = πr^2h, where r is the radius of the tube and h is the height (or length) of the tube.


What volume of water is there in a meter of 22mm pipe?

The volume of water in a pipe can be calculated using the formula: volume = area x length. For a 22mm pipe, the area can be calculated using the formula for the area of a circle: πr^2, where r is the radius (11mm). The length of the pipe in this case is 1 meter. By substituting these values into the formula, you can calculate the volume of water in the pipe.


Formula to find length of volume?

To find the length of a volume, you need to know the volume's dimensions. The formula to calculate the volume of a rectangular solid (length × width × height) can help determine the necessary length if the other dimensions are known.


Which star is the densest Antares spica or polaris?

Look up information about each star's mass and diameter, calculate the volume, and calculate mass / volume. Or simply assume that the star with the smallest diameter has the largest density. This is usually the case, since the stars' mass varies way less than their volume.


.75 diameter x 3m length how many cubic meters?

To calculate the volume of a cylinder, use the formula V = πr^2h, where r is the radius and h is the height. Given a diameter of 0.75 (which is equivalent to a radius of 0.375) and a height of 3m, the volume would be π(0.375)^2(3) ≈ 1.33 cubic meters.

How do you find the diameter of a cylinder when you only know the length?

If you only know the length, and nothing else, you can't. If you know the length and the volume, you can calculate the diameter.


If you know the volume of a cylinder how do you calculate dimensions?

To calculate the volume of a cylinder, first determine the height or length of the cylinder as well as the diameter. Divide the diameter by two to get the radius, then use this formula:Volume = radius2 x Pi x length (or height)


How do you calculate the mass given diameter and length?

You cannot. Diameter and length can, for some particular shapes, give you the volume. But that will not give you the mass unless you know the density of the substance.


How do you calculate volume flow?

If you are trying to find the volume of something, remember there is a formula which is volume = length times width times high.


How do you calculate the volume of water in a pipe?

You need to know the radius (1/2 the inside diameter) and the length of the pipe. Then, you use this formula to calculate the volume:Pi (3.1416) x r2 x length


How do you calculate column volume?

Multiply column inside diameter by the column's length. Then convert to units you need. The above is not correct.The volume of a column is the circular area of the column multiplied by the length, pi*radius^2*length.


How do you calculate the mass of a hollow tube?

To calculate the mass of a hollow tube, you need to know the outer diameter, inner diameter, and length of the tube. First, calculate the volume of the tube by subtracting the volume of the inner hole from the volume of the outer cylinder. Then, multiply the volume by the density of the material to determine the mass.

How do you calculate the water volume in pipe line volume?

Calculate the (diameter of the pipe (D) divide by 2) squared X pi * length and this will give you the volume. eg Volume = (D/2)2 X Pi X Length. (or R2 X Pi X Length) (Use 3.14159265359 as an approximation for Pi.) In practice, 11/14 Times Diameter is used in lieu of (R2 X Pi) as a quick and dirty but near enough approximation.
