Frequently Asked Questions
In technical contexts, they are often used interchangeably. However, 'cruising radius' more explicitly emphasizes the round-trip distance from a starting point, while 'range' can sometimes imply a one-way distance.
Yes, it's perfectly applicable. 'The electric vehicle's cruising radius drops significantly in cold weather' is a correct technical usage, though 'range' is more common in consumer contexts.
No. It is a specialised term from naval/aviation/military contexts. In everyday conversation, people would simply say 'how far it can go on a tank of fuel' or use the word 'range'.
They are virtual synonyms in military and engineering terminology. 'Radius of action' is perhaps slightly more formal and comprehensive, potentially including time factors, while 'cruising radius' is closely tied to the act of cruising (traveling at an efficient speed).

Mnemonic
Imagine a ship drawing a perfect CIRCLE around its home port on a map. The RADIUS of that circle (the line from the centre to the edge) is how far it can CRUISE out and still get back.
Conceptual Metaphor
RESOURCES ARE FUEL / SCOPE IS A CIRCULAR AREA. The concept maps the abstract idea of limited scope onto the concrete, spatial image of a circle's radius defined by a finite fuel supply.
