Formulas Used in the Calculator
Understanding the formulas can help you verify results:
Circle
- Area = π × r²
- Circumference = 2 × π × r
Rectangle
- Area = Length × Width
- Perimeter = 2 × (Length + Width)
Triangle
- Area = ½ × Base × Height
Practical Examples
Example 1: Calculating Area of a Circle
Imagine you want to calculate the area of a circular garden with a radius of 5 meters.
- Input radius = 5
- Click Calculate
Result:
- Area ≈ 78.54
- Circumference ≈ 31.42
This helps you estimate how much grass or fertilizer is needed.
Example 2: Measuring a Room (Rectangle)
You are planning flooring for a room:
- Length = 10 meters
- Width = 8 meters
Result:
- Area = 80 square meters
- Perimeter = 36 meters
This is useful for buying tiles or carpets accurately.
