Imagine a stone henge from 3500 years ago. The outer circle consists of 30 stones, each standing 4m tall, 2m wide, and 1m thick. If the circle containing this regular polygon was 33m in diameter, approximately how far apart are the outer stones??

Answer 1

The circle is 33*Pi around. The stones take up 2*30 of this distance. The amount not taken up is

amount available= 33PI-2*30 m

dividing this up into 30 spaces is then

(33PI-60)/30 meters between

check my thinking.
