Pi week: going full circle - Part II

Consider a circle that is 1 foot in radius (from the center to the outside). Then this circle must be 2 feet in diameter. Using our formula for the circumference, C = d x pi, gives us a circumference of 2 x pi. But how would we measure this? Does there ...What is the best foundation for the existence of objective moral values–theism or atheism?

It feels a lot like two people arguing about which is the best way to calculate the circumference of a circle: multiply the diameter of the circle times pi (C = pi*d) or double the radius and then ... argue that the first formula is best, because it ...- Want to make the calculation for yourself? Well, the formula for calculating the circumference of a circle is 2 x pi x r, where R is the radius of the circle. The equatorial radius of Saturn is 60,268 km, so you can do the math yourself. Of course ...

Now, finally, we can go on to the circle which, I hope you will all remember from school, is defined by ?, having a circumference equal to it times two times its radius (r), and an area equal to it ... I typed "here's" as "here'x"--which I'm now unsure ...Why we have to get rid of pi for the sake of good math

Well, simply enough, it's 2*pi, or 2π . Whereas pi is defined as the circumference of a circle divided by its diameter (C/D=π), tau is defined as the circumference divided by the radius (C ... For instance, the area of a circle formula (A = πr^2 ...
