How To: Create a circle with a specific radius


In some instances, a circular measurement with a specific radius is used to highlight certain information on a map and to emphasize other features that are present in the specified circular zone. For example, creating a circular measurement with a radius of 3km and a manufacturing plant as the input point to locate the features present within the radius.


This workflow is only applicable to ArcGIS for Desktop versions 8.x, 9.x and 10.0.
For later versions of ArcGIS for Desktop, refer to the following link: ArcGIS Help 10.3 - 10.6: Creating a circle feature
