Pi can be equal to whatever you want, as long as you’re using a number base that accounts for it. Pi is only an irrational number because base-10 is a rational base. You could create a number base that sets pi equal to 1, if you wanted.
American Bison, too. The repopulation of American bison (often mistakenly called buffalo) is one of the most successful repopulation efforts in history. The reason you’re able to order buffalo (again, not actually buffalo) burgers at your local hipster burger joint is because American bison is no longer endangered. The population has come from less than 1000 total bison (all privately owned by a handful of conservationists) to over 400k today.
That’s exactly my point. A base pi system would have pi equal to 1. In a base pi number system, a circle with a radius of 1 would have a circumference of 10. A radius of 10 would be a circumference of 100. Etc… Pi (and the relationship between a circle’s radius and circumference) only normally requires complex math because base 10 is a rational number base.
