Answer:
1/4th
Step-by-step explanation:
This comes from knowing the unit circle in both radians and degrees. However, you could also calculate it from knowing that 360 degrees is 2 radians. What you'll find is that radians is 90 degrees, or 1/4th of the circle. This means that an arc measuring radians will be 1/4th of the entire circumference.
I hope this helps!
