Answer:
π m
Step-by-step explanation:
Arc length = 2πr[tex]\frac{0}{360}[/tex]
where r = radius and 0 = central angle
The given radius is 4m and the given central angle is 45°
Thus, arc length = 2π4[tex]\frac{45}{360}[/tex]
* simplify *
( note when simplifying we leave our answer in terms of π as the answer choices do. )
2 * 4 = 8
[tex]8\frac{45}{360} =1[/tex]
arc length = 1π
Hence, arc length = 1π or just π
