The Annulus Area Calculator is a handy tool for figuring out the space between two circles that share the same center, creating what we call an annulus. Let’s uncover the formula, walk through the steps, and see why calculating annulus area is useful.
Annulus Area Calculator
Formula and Variables:
The formula for finding the area of an annulus is given by:
$\text{Annulus Area}=\mathrm{\text{Unknown node type: span}}\times ({R}^{2}{r}^{2})$
 Annulus Area: Represents the total space between the two circles, measured in square units.
 R (Outer Radius) and r (Inner Radius): Stand for the radii of the outer and inner circles, respectively, measured in the same units as the annulus area.
 π (Pi): A constant (around 3.14159) used in the calculation.
StepbyStep Calculation:
To calculate the annulus area, follow these steps:

Input Radii:
 Get the values for the outer radius (R) and inner radius (r) of the annulus.

Apply the Formula:
 Use the formula $\text{AnnulusArea}=\mathrm{\text{Unknown node type: span}}\times ({R}^{2}{r}^{2})$to find the total annulus area.
