Can I construct sentences using the word radius like the following sentences?

1) How much radius can the walkie-talkie cover?
2) The walkie-talkie work in how much radius the best?

1) How much radius can the walkie-talkie cover?
2) The walkie-talkie work in how much radius the best?

1) Your example would be understood but I think the simpler
"What radius can the walkie-talkie cover?" is more natural.
or: "How wide a radius can the walkie-talkie cover?"
2) "Within what radius will the walkie-talkie work best?"

not a teacher

Or simply "what's the working area/radius?"

Hi,

I feel "radius" to be too "Latin" for this context (I would understand it better if used in the context of a dicussion on Geometry, for instance). Why not simply ask about its span? Would that work?

:up: Coverage?

Span would not work, in my opinion. "What is the range of this walkie-talkie" would.

"Radius" is quite normal when talking about a point source, like a radio. Radio station WXYZ can be heard anywhere within a 25 mile radius.

However, the point of this thread is a walkie-talkie, which I'm not sure it is a "source point".

What is a walkie-talkie other than a radio? A two-way radio. When it transmits it goes out equally to all directions.

I, too, find nothing odd about using "radius" this way, but you can say "range" if it makes you happier.

:up: On reflection (sorry, charliedeut ;-)) I withdraw my support for the word 'span'.

Nah, never mind. ;-) Todays is just one of those days when everything one attempts backfires :-( I think I'll be going to bed early, just in case ;-)
