At the farmer's market, there is a scale that measures the weight of fruit and vegetables. The needle is 16 cm long, and it rotated 68° when Danielle placed six oranges on it. How far did the needle travel as it rotated? How would I do this one?

Best ResponseYou've already chosen the best response.1he needle is the radius of a circle. The distance it rotates is a portion of the circumference. Since there are 360° in a circle, multiply this by 68/360. The answer is then found as 16*2π*(68/360). That comes out somewhere below 20cm. Do it yourself in Excel to get the real answer. Doesn't that give you 18.98918226 (which is really 19cm)?
