Which command can you use to dimension the radius of a circle?

The command used to dimension the radius of a circle is DIMRADIUS. This command allows you to specifically indicate the radius measurement of a circular object in your drawing, providing clarity on the size of the curve in a precise manner. When you invoke this command, it prompts you to select the circle for which you want to display the radius, ensuring that the dimension is accurately positioned and clearly presented in your layout.

Using DIMRADIUS is particularly beneficial in technical drawings, where understanding the radius is crucial for manufacturing, fabrication, or construction purposes. This precision ensures that all stakeholders can interpret the dimensions correctly and apply them as intended, making it an essential tool in the AutoCAD software.

The other options serve different purposes; for example, DIMLINEAR is used for linear dimensions, DIMCIRCLE is not a standard command in AutoCAD, and DIMDIAMETER is used to display the diameter of a circle rather than the radius. Each command has its specific application in the dimensioning process, but to measure a circle's radius, DIMRADIUS is the appropriate and effective choice.
