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.
