The radius of a circle is 6 kilometers. What is the length of a 75° arc?

Answer:
7.85km
Step-by-step explanation:
Given data
Radius= 6km
θ= 75°
Arc length = 2πr (θ/360)
substitute
Arc length = 2*3.142*6 (75/360)
Arc length = 2*3.142*6*0.2083
Arc length = 7.85 km
Hence the length of the arc is 7.85km
