Annulus Circle

by Donald Schaefer

The Annulus Circle App computes the number of square units it takes to completely fill an annulus. This area is computed from an Outer Radius and Inner Radius whereby: Area = π(R1² - R2²)

This app also computes a quadratrure rule whereby for the computed result: R1² less Computed Result less R2².

A graphical representation of the circle radii and area is presented.

Annulus circle has versions for iPad, iPhone and Apple Watch.
