To determine the diameter of a rod a student wound a thread 5 times round the rod and measured the length of thread as 156 mm on a metre scale. Using this value he calculated the diameter of the rod. If the actual diameter of the rod is 9.94 mm, what is the error that could result in the method followed by the
student? Take `(pr+q)/(2)`
