Math CentralQuandaries & Queries


Question from Firdous, a teacher:

I found the circumference but after what to do I am not getting the question is. The diameter of the sarsen circle is 33 meters, since there were originally 30 sarsen stones located on the circumference, how far apart would the centres of the stones have been? Round to the nearest tenth of a meter.


Imagine that you place a dot on the circumference at each place where the centre of a stone is to be. Thus you have 30 equally placed dots around the circle. These dots then divide the circumference into 30 pieces of equal length. How long is each piece?
