📌 Definition: Elliptical Shape Area
An ellipse is a closed curve defined by two axes: the semi-major axis (a) and the semi-minor axis (b). The total area of an ellipse is given by the formula:
A = π × a × b
This calculator helps determine the area of an ellipse based on the lengths of its axes.
📌 Key Formula
For an ellipse with:
- Semi-major axis (a)
- Semi-minor axis (b)
The area (A) is calculated as:
A = π × a × b
📌 Examples of Calculations
| Parameters | Formula | Example Calculation |
|---|---|---|
| a = 5, b = 3 | π × 5 × 3 | ≈ 47.12 |
| a = 7, b = 4 | π × 7 × 4 | ≈ 87.96 |
🔧 Practical Applications
1. Engineering & Architecture: Calculating the area of elliptical windows, arches, and domes.
2. Agriculture: Estimating the area of elliptical plots of land.
3. Astronomy: Used in determining the area of elliptical orbits.
❓ FAQs
Q1: What is the area of an ellipse?
✅ The area is calculated using A = π × a × b.
Q2: What do “a” and “b” represent?
✅ “a” is the semi-major axis and “b” is the semi-minor axis of the ellipse.
Q3: Can this formula be used for circles?
✅ Yes, when a = b, the ellipse becomes a circle, and the formula becomes A = π × r².
Q4: How do I measure the axes of an ellipse?
✅ The axes can be measured by determining the longest and shortest radii from the center to the perimeter.
Q5: Are there any units required for a and b?
✅ The units for a and b must be the same (e.g., meters, feet) to ensure the area is correctly computed in square units.
