1. Polygon in Annulus

2. You have two figures that each show a regular polygon (with a given side length) just touching two circles. What is the area of the annulus, i.e. the area enclosed by the circles, in terms of  ?

3. Each figure shows a regular polygon (with a given side length) just touching two circles. What is the area of each annulus, i.e. the area enclosed by the circles, in terms of  ?

12. All the same area as this!
