To adapt the formula for use with the diameter, you substitute d/2 for r in the standard equation. Deriving the Half Circle Area Formula The foundation of the area of half a circle formula lies in the universal equation for the area of a complete circle, expressed as A = πr², where π (pi) is a mathematical constant approximately equal to 3.
