1/6 for the first question and 1/3 for the second
The arc length, radius and the included angle are related as
where 
is in radians.
The radius 
is given by
Correct choice is (B).
Answer:
95.49°
Step-by-step explanation:
The arc length formula is s = rФ, where r is the radius and Ф is the central angle in radians. Here, r = 9 ft and s = 15 ft. Thus, the central angle Ф is
Ф = (15 ft) / (9 ft) = 5/3 radians, or
5 rad 180°
------- * ---------- = 95.49°
3 π rad
