Spiral of Half Equilateral Triangles with Inscribed Circles Using Dr Geo (png image file)

Half equilateral triangles (30°-60°-90° triangles) are positioned recursively, with the side of one triangle being equal in length to the hypotenuse of the next. A circle is inscribed in each triangle. Calculate the area of the ninth circle relative to the first circle. The data file for Dr Geo is also on i2geo.net as Spiralofhalfequilateraltriangles.drgeo
