Central is an adjective, not a noun. So the question depends on central what? And since you have not bothered to provide that crucial bit of information, I cannot provide a more useful answer.
A twelve sided polygon is called a dodecagon.
A twelve sided polygon is called a dodecahedron. No, that is a twelve faced solid (3-D) object. A 12 sided polygon is a dodecagon.
It will have 12 sides

30
360 degrees ( all the way round the central point). However, for one given sector it is 360/12 = 30 degrees.

A twelve-sided polygon is called a dodecagon.
Twelve. The number of sides and vertices in a polygon are always the same.
If the 12-sided polygon is 'regular', then each of its exterior angles is 30 degrees. Whether the polygon is regular or not, all 12 of its exterior angles still add up to 360 degrees, but they may not all be equal.
