Title: Useless factoid of the day

If the diameter of a circle equals pi then its circumference equals pi squared and its area equals pi cubed. A cubic area! My lord the world makes no sense!

R=½π
Circumference = 2πR = 2π*½π=π2
Area of Circle = πR2 = π*(½π)2 = ¼π3

π is dimensionless, so it can make sense. ;)

However, always thought it was an interesting relationship
