Volume of three shared cylinders

In summary, the problem is to calculate the volume of the space enclosed by three cylinders, with equations x^2+y^2=1, x^2+z^2=1, and y^2+z^2=1. The suggested approach is to use a triple integral and change to polar coordinates, but there is some debate about whether this is the best method. There is also discussion about the range of z and how it relates to the equations.

If x^2+z^2=1 and y^2+z^2=1 then x^2=y^2=1-z^2. The cross sections of your surface are squares integrating dz. I definitely wouldn't change to polar coordinates.

Those are the values for single value of x. Suppose you consider all possible x?
 

1. What is the formula for calculating the volume of three shared cylinders?

The formula for calculating the volume of three shared cylinders is V = πr²h, where V is the volume, r is the radius, and h is the height of the cylinder.

2. How do you find the total volume of three shared cylinders?

To find the total volume of three shared cylinders, you can simply add the volumes of each individual cylinder. So, Vtotal = V1 + V2 + V3.

3. Can the three shared cylinders have different dimensions?

Yes, the three shared cylinders can have different dimensions. The formula for calculating the volume will still be the same, but you will need to use the respective dimensions for each cylinder in the calculation.

4. Are there any other methods for finding the volume of three shared cylinders?

Yes, there are other methods for finding the volume of three shared cylinders, such as using the cylindrical shell method or the disc method. However, the formula for calculating the volume will still involve the dimensions of the cylinders.

5. How can the volume of three shared cylinders be useful in real-life situations?

The concept of the volume of three shared cylinders can be useful in various real-life situations, such as calculating the volume of a storage tank with multiple compartments, determining the capacity of a cylindrical container with partitions, or estimating the volume of overlapping cylindrical objects in engineering or design projects.
