Backend Formula for the Hole Area Calculator
The underlying formula for calculating the area of a hole is based on the mathematical equation for the area of a circle: Area = π × radius². This formula requires precise input of the radius to ensure the accuracy of the calculated area. For instance, if you have a hole with a radius of 5 cm, the area calculation is: Area = π × (5)² = 78.54 cm². Different variations of this formula may involve calculating based on the diameter, using the formula: Area = π × (diameter/2)².
