Find the length of the arc.
A. 15π mi
B. 5400π mi
C. 135π mi
D. 125π16 mi

Answer:
A. 15π mi
Step-by-step explanation:
First find the circumference
C = 2*pi*r
C = 2 * pi*18
C = 36pi
The arc is 150 degrees
The fraction of the circle is
150/360 = 5/12
Multiply this by the circumference
5/12 * 36 pi
15 pi
