1. What is the Area of Annulus?

The Area of Annulus is defined as the area of the ring-shaped space i.e. the enclosed region between the two concentric circles. It represents the difference between the areas of the outer and inner circles.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( A \) — Area of Annulus (m²)
• \( \pi \) — Archimedes' constant (≈3.14159)
• \( b \) — Breadth of Annulus (m)
• \( r_{Inner} \) — Inner Circle Radius of Annulus (m)

Explanation: This formula calculates the area of the annular region using the breadth of the annulus and the radius of the inner circle.

3. Importance of Annulus Area Calculation

Details: Calculating the area of an annulus is important in various engineering and architectural applications, particularly in designing ring-shaped structures, pipes, washers, and other circular components with hollow centers.

4. Using the Calculator

Tips: Enter the breadth of the annulus and the inner circle radius in meters. Both values must be positive numbers. The calculator will compute the area of the annulus in square meters.

5. Frequently Asked Questions (FAQ)

Q1: What is an annulus?
A: An annulus is a ring-shaped object or region bounded by two concentric circles.

Q2: How is the breadth of annulus defined?
A: The breadth of annulus is defined as the shortest distance or measurement between the outer circle and inner circle of the annulus.

Q3: Can this formula be used for any annulus?
A: Yes, this formula works for any annulus where you know the breadth and the inner circle radius.

Q4: What are practical applications of annulus area calculation?
A: This calculation is used in mechanical engineering (washers, seals), architecture (ring-shaped structures), and physics (calculating areas in circular motion problems).

Q5: How accurate is this calculation?
A: The calculation is mathematically exact, assuming precise measurements of breadth and inner radius.
