Working Principle

This calculator uses basic geometric formulas to calculate the area and circumference of a circular hole:

  • Area: The area of a circle is calculated using the formula π * (radius)², where radius is half the diameter.
  • Circumference: The circumference of a circle is calculated using the formula π * diameter.

Applications

This calculator can be used in various fields such as:

  • Engineering and construction for calculating hole sizes in metal or plastic materials.
  • Manufacturing for determining the required size of drill bits or punch tools.
  • Geometric and mathematical education for understanding basic circle properties.
