Find ways to understand something better
Either 2 or 4. I’m leaning closer to 4 though. My answer would be 4.
The plural form of the word radius is <em>radii</em>.
I know it sounds weird, but this is correct. Adding <em>-s </em> at the end of the radius would make the word grammatically incorrect. This is because the word radius itself is a Latin word.
