S = 15.47 units
Step-by-step explanation:
First, convert the degree angle into radians:
68° × (π/180) = 1.19 rad = theta
The arc length S is given by
S = r × theta
= (13 units)(1.19 rad)
= 15.47 units
Answer:
15.43
The formula = angle / 360 × circumference
= angle / 360 × pi diameter
= 68 / 360 × pi × 13 + 13
= 68 / 360 × pi × 26
= 17 / 19 × pi × 26
= 221 / 45 pi
= 15.43
