1
Step-by-step explanation:
We are given that

Numbers are in radians
Substitute x=-1

Substitute x=-0.25

Substitute x=-0.01

Substitute x=-0.005

Substitute x=0.005

Substitute x=0.01

Substitute x=0.25

Substitute x=1

Therefore, 
Hope this can help you. I tried to solve each one out and I tried to write notes on how I got the equation and the answer. Message me if you can't read something, my handwriting tends to be messy :)
Answer:
18
Step-by-step explanation:
There is a string that is 3 yards long that is divided into pieces that are 1/6 of yard long. Divide the total length by the length it was divided into to find the number of pieces.
