Our mechanics professor in university told us that Pi squared is ten and 6xPi=20. He said "engineers do not care for the fourth digit after the dot. If you want some number very precisely calculated just hire a mathematician instead because they are cheaper per hour"
Multiple people have brought this up and I just don't get it. When would you ever use Pi squared for anything, and if you'd never use it, who cares what its value is?
The only thing I could come up with is marking out an area by rolling a wheel some number of times to measure each edge.
Long ago, I memorized the square root of pi precisely because it seemed like the least useful number I could think of. (I was frustrated by something. Never mind.) But pi squared seems like it's pretty much the same in terms of usefulness.
If you said pi is the square root of 10, then I could see the value. Maybe that is what is being implied?
