the size of the fillet is determined by setting the desired _________.\narc\ndepth\nradius\ncircumference
Answer
Brief Explanations:
In engineering and design, the size of a fillet (a rounded - edge) is determined by its radius. The radius defines how sharp or rounded the corner is. An arc is a part of a circle, depth is not the standard measure for fillet size, and circumference is the perimeter of a circle which is not relevant for defining fillet size.
Answer:
C. Radius
