# "Ένας κύκλος δεν έχει μόνο μία ακτίνα."

## Translation:A circle does not have only one radius.

This seems like a very odd thing to say, though it is technically correct. On a diagram of a circle you can have more than one radius. I think the reason why this sounds so strange to me is that a radius on a diagram is quite different from the measure of a radius (which is the the same for all the radii in a circle by definition), which is frequently just called 'the radius' in English. I found it a very confusing sentence to translate into English for this reason.

No, I am still puzzled. If you start from the center of a circle and measure outward you get the radius. You can do this numerous times, but the result will always be the same. These aren't varying radii, but the same radius. A circle really can only have one radius. But hey, I am here to practice Greek, even if the logic is a little wonky

So we would say that a circle has infinite radii, but all of identical length?

We are not trying to present ready-made sentences but to give you a wide vocabulary so you can make your own sentences. Now, as for the factual correctness of the you have an error.

Here is what the Greek says...see the top of this page.

Your translation does not include all the information.

"Ένας κύκλος **δεν έχει μόνο μία ακτίνα**."

Translation: "A circle **does not have only one radius**.

That is different from..."A circle **does not just have a radius.**"

My Athenian consultant, a scholar of the classics, sees my point, but explained to me that the sentence makes sense classical geometry, where radii are viewed as a series of little spokes extending from the centre of the circle, whereas a radius in modern geometry is viewed as the length from the centre and to any point on the circumference of a circle, and hence is singular.
