Answer:
15 pi
Step-by-step explanation:
The circumference of the circle is given by
C = pi * d
C = pi *18
We are subtracting part of the circumference that covers 60 degrees
The entire circle is 360 degrees
60/360 = 1/6
We are subtracting 1/6 of the circumference
1/6 *18pi = 3pi
We have 18pi and subtract 3pi = 15pi
The dark shaded arc is 15pi
