Answer:
D
Step-by-step explanation:
∠ 6 is formed by the 2 lines that intersect at D
then the vertex of ∠ 6 is D
The circumference is (2 pi) (radius) . The ratio of radius to circumference is (1)/(2 pi).
Circumference of a circle:
C = 2 r π;
Length of an arc:
L = r π α / 180°
L = r π · 30° / 180° = r π /6
r π /6 : 2 r π = 1/6 : 2 = 1/12
Answer: A ) 1/12
