No, that's not too obvious. As has already been pointed out, you're going to need a circle the size of a building if you want to get more than 2-3 digits of precision (assuming that you can make your measurements with millimeter accuracy). How are you going to verify that your inscribed circle has no serious imperfections? Try making a building-sized circle on the ground using string -- it will be off of true by much more than a millimeter, I assure you.
- foobarian 12y agoAt one point doing some field experiments I needed to measure out a large distance very precisely, and found that using construction measuring tape (the fiber glass kind from Home Depot) has problems because of stretch. And really any kind of material will have enough elasticity to cause problems for long measurements. I ended up making a tensioner to ensure I always took the measurement at about the same force. Getting high precision gets complicated and expensive real fast!
