What is the exact length of arc AB?

dsp73

Answer:

π m

Step-by-step explanation:

Arc length = 2πr $\frac{0}{360}$

where r = radius and 0 = central angle

The given radius is 4m and the given central angle is 45°

Thus, arc length = 2π4 $\frac{45}{360}$

* simplify *

( note when simplifying we leave our answer in terms of π as the answer choices do. )

2 * 4 = 8

$8\frac{45}{360} =1$

arc length = 1π

Hence, arc length = 1π or just π
