Regular polygon can be incribed in a circle of radius equal to its side.
so if you join all the vertices to the centre, you will get 6 equilateral triangles. each interior angle will have 2 angles of 60 each. thus interior angle = 120
exterior angle=180-120=60

Answer:
452.16cm squared
Step-by-step explanation:
Area for a circle formula is A = pi * r^2
Area = 3.14 * 12^2
Area = 452.16
