Understanding the Math
The Annulus Area Calculator computes the result using fundamental principles of mathematics. Calculate the area of an annulus (ring).
Formula Definition
Result = π × ((R × R) - (r × r))
This formula is applied directly to the inputs provided above. Ensure all units are consistent (e.g., all lengths in meters) before calculation to guarantee accuracy.
Example Problem
Given:
- Outer Radius (R) = 11
- Inner Radius (r) = 3
Solution:
Substitute values into the formula:
Result = π × ((11 × 11) - (3 × 3))
Quick Notes
- Double-check input units. Inconsistent units (e.g. feet vs meters) will yield incorrect results.
- Calculations are performed with high-precision floating point arithmetic.
