Best practice

When describing a specific area affected by something, use "within a radius of" to clearly define the boundaries. For example, "The evacuation zone is set "within a radius of" 5 kilometers from the chemical spill."

Common error

Ensure you're using the correct measurement. The radius is the distance from the center to the edge of a circle, while the diameter is the distance across the entire circle. Using the diameter instead of the radius will double the area you're describing.

Linguistic Context

The phrase "within a radius of" functions as a prepositional phrase that modifies a noun, specifying the extent or limit of an area defined by a circular boundary from a central point. As Ludwig AI confirms, the phrase is both correct and usable.

What is a good alternative to "within a radius of"?

Is it more appropriate to use "within a radius of" or "within a diameter of"?
