If they are beyond repair, I cut them off with a thin metal cutting disc in an angle grinder.
Very little ! With no identifying markings at all - it's essentially just a small metal disc !
No When a right cylinder is viewed at right angle to its axis the projected form can be a square or a rectangle, which have 4 right angles. The same applies if the cylinder is cut through on any plane parallel to its axis.
Area of disc: pi*6^2 = 36*pi square cm
Pi*6 * * * * * Independent of the radius? Makes no difference if the disc is twice as wide? I think not! It is actually 2*pi*r2 where r is the radius of the disc.
An angle grinder is a hand-held grinder, a power tool with an abrasive disc, used for grinding, cutting and polishing.
I generally use an angle grinder with a thin steel cutting disc. Sometimes I use a hacksaw, but my small angle grinder is pretty versatile and saves a lot of time.

You need an 'abrasive fibre cutting disc', rather than a saw. I usually have one in my small angle grinder for cutting steel.
I cut it with an abrasive fibre cutting disc on my angle grinder. I also cut all pipes this way, very fast and a clean cut.
As long as it fits the arbor, yes.
The simplest way would be to use a grinder with a cutting disc and just cut the pipe off.
There are nine blades that can be used for a circular saw. Ripping, crosscutting, combination, plywood, hollow ground, dado, thin kerf, abrasive, and diamond are all blades that can be used to cut wood, glass, steel, and concrete.
Disc angle has main two angle : 1. Vertical angle 2. Horizontal angle
Brick veneer that is in place and needs to be cut, such as to create a new opening, is usually cut with a circular saw and a masonry blade. For smaller cuts, an angle grinder and cutting disc can be used. Some saws are specially set up for masonry cutting, and spray water on the masonry while they cut, to keep the blade cool. Do not try to do this with a saw that is not designed for wet cutting. It may short circuit and electrocute you. Bricks that are not in place can be cut with a saw or grinder, and some can be cut by being struck with the right hand tool (like a bolster) applied with a skilled hand.
The answer is it can be less. Most grinding discs show the maximum RPM allowed, it does not necessarily mean that you have to run at those RPM it means that in order to use the disc SAFELY you should not exceed that speed.
Anybody that cuts metal uses a hacksaw sometimes. - Many of us who are lazier now use a small angle grinder with a 'cutoff' disc instead,
