Answer: option A is the correct answer.
Step-by-step explanation:
The formula for determining the length of an arc is expressed as
Length of arc = θ/360 × 2πr
Where
θ represents the central angle.
r represents the radius of the circle.
π is a constant whose value is 3.14
From the information given,
Radius, r = 4 miles
θ = 140 degrees
Length of arc = 140/360 × 2 × 3.14 × 4
Length of arc = 9.8 miles to the nearest tenth
