[Aiylish]

The curved surface area of a length of cylindrical cable is 19m2. Calculate the length of the cable, l, to the nearest metre.
The answer is suppose to be 121 m. I need to know how to solve this question.

Is that the complete statement of the problem?

No other information - e.g. diameter or gage of the cable - is given!
