Why is Pi half a circle?

Since the radius is half the diameter, and pi is the ratio of the circumference to the diameter, there will be pi times two radians to the angle of a full circle. Thus, pi radians make a half circle.

Which is better tau or pi?

π is how many diameters of a circle are in its circumference. This would be a good constant to use if we had our equations in terms of d (diameter) rather than r. But τ is how many radii of a circle are in its circumference, and it fits better with equations in terms of radius.

Is zero a real number?

Real numbers can be positive or negative, and include the number zero. They are called real numbers because they are not imaginary, which is a different system of numbers.

Is 0 A whole number?

The whole numbers are the numbers 0, 1, 2, 3, 4, and so on (the natural numbers and zero). Negative numbers are not considered “whole numbers.” All natural numbers are whole numbers, but not all whole numbers are natural numbers since zero is a whole number but not a natural number.

Will Pi ever be solved?

Technically no, though no one has ever been able to find a true end to the number. It’s actually considered an “irrational” number, because it keeps going in a way that we can’t quite calculate.
