Dear tutor  @Math_Therapy,  when this writer/(problem's composer) wrote 

    "Express the arc length in terms of . . . "

he / (or she),  OBVIOUSLY,  wanted to say  " in terms of the arc angular measure ",
but,  OBVIOUSLY,  forgot  (or did not know)  these words.


I am able to read between the lines,  as well as between the words,  too . . .

I do it very easy; it is not difficult to me . . .
