Answer:
C
Step-by-step explanation:
The length of arc AC (L) is calculated as
L = circumference of circle × fraction of circle
= 2πr × 
= 2π × 12 × 
= 2π × 5
= 10π ≈ 31.42 → C
Answer:
See below
Step-by-step explanation:
The interval must be chosen so that the function is one-to-one, and the sine and cosine functions are not one-to-one on the same intervals.
