Photoshop
In Adobe Illustrator, you can show the radius of a shape by using the "Measure Tool" or by creating a circle with the "Ellipse Tool" and then drawing a line from the center to the edge, indicating the radius. You can also create a text box to label the radius with the appropriate measurement. In Adobe
Photoshop, you can use the "Ruler Tool" or simply draw a line and use the "Info Panel" to display the length of the radius.
