At one time I knew pi to thirty places. Then I read somewhere that it really doesn’t need to be that precise. So for example, if you were measuring the circumference of the earth using π = 3.14159 vs π = 3.141592653589793 it only changes the circumference by fractions of a millimeter at this scale. I can’t measure a 24 inch piece of wood with that amount of accuracy.
sqrt 2 = 1.4142135623730950884
sqrt 3 = 1.732050808
sqrt 5 = 2.236067978
sqrt 6 = 2.664(?) i think
sqrt 7 = ?
sqrt 8 = 2.828
sqrt 10 = 3.166
recited from memory, remembered since i was 13 or sth idk, i was bored back then.

The circumference of the Earth is somewhat subjective at that scale anyway, since it also depends on where you decide the radius stops.
Well yeah since we really aren’t a perfect sphere. Not to mention elevation, buildings, etc.
Why don’t you know 7, also 6 is wrong
What they had for 6 is closer to 7
