How can I properly use the phrase "within a 2" in a sentence?
To use "within a 2" correctly, specify the unit of measurement you are referring to. For example, use "within a 2-mile radius" or "within a 2-week period". Using the phrase without a unit of measurement, like just saying "within a 2", is grammatically incorrect.

Instead of "within a 2", you can use phrases like "within two units", "within a couple of", or "in less than two" followed by the appropriate unit of measurement.

No, it is not correct. You need to specify the time frame. For example, you should say "the event happened "within a 2-hour window"" or "the event happened "within a 2-day period"".
What is the difference between "within a 2-mile radius" and "within a 2-kilometer radius"?
"Within a 2-mile radius" refers to a circular area extending 2 miles from a central point, while "within a 2-kilometer radius" refers to a circular area extending 2 kilometers from a central point. The difference is simply the unit of measurement used to define the extent of the area.
