    YES
    If you flatten the cylinder - you get a rectangle...4 cm by 12 cm
    There are four 3 4 5 right triangles.

    the sum of the hypothenuses (is that right??) is 20 cm

    There's one issue I see here though, what you labelled 4cm is the diameter, the question states that the circumference is 4cm. Circumference =/= diameter, so either 20 is incorrect or the question is phrased incorrectly.

    Edit: Took a closer look at the question, I see where I went wrong. 20 is the correct answer.

    The answer is simple that's why we hire them Singaporeans to do all the smart work while we chill in Bahamas....

    You guys realize 16 will only get you around the rod four times, but it won't get you across, right?

    That wasn't very nice. I can ask you a question I am sure you will get wrong, yet are you a "retard"?

    People have different strengths and weaknesses. Kindness makes the world go round.

    Also, looking up an equation on Google does not make you smart. Being able to calculate that will get you no where in life unless you are an engineer.
