# Annulus Area Calculator

Posted by Dinesh onThis calculator calculates the **area of annulus (a)** using radius of the outer circle (r), radius of the inner circle (h) values.

## Annulus Area Calculation

### Formula:

A = π × (R^{2} - H^{2})

A = Area of Annulus (Annular)

R = Radius of the Outer Circle

H = Radius of the Inner Circle
