I assume you're referencing the mathematical problem of "squaring the circle." Engineers use increasingly precise values of pi (more digits) to estimate the volume/area required; as the requirement for precision increases, more digits are used.
For example, if an engineer needed to replace a rectangular pipe with a cylindrical one (and maintain the same volume), he would determine how precise the new fitting had to be to maintain functionality, and then use an appropriate value for pi.
(In a very loose comparison, perhaps the value 3.14 would be used for an outdoor water system, and 3.1415927 would be used for a life-support system on the International Space Station.)

On the one I'm working on if you follow the tube out of the condenser (on the passenger side), it goes to this aluminum block. This aluminum block has a nut on it. Taking that block apart will reveal the orofice tube.
To calculate the cross sectional area of a rectangular tube, multiply the widths of two adjacent sides of the tube.

A drawn aluminum tube is a seamless tube produced by drawing a solid aluminum billet through a die to achieve the desired dimensions and properties. This process helps to maintain a consistent wall thickness and smooth surface finish, making it suitable for various applications such as construction, automotive, and aerospace industries.

It depends on the cause of the issue. If the tire is damaged or worn out, you may need to replace both the tire and the tube. If only the tube is punctured, you can just replace the tube.

It depends on the dimensions of the tube, but the question did not provide all of them.
