Answer: the length of the arc is 15.17π feet
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 = 13 feet
θ = 210 degrees
Therefore,
Length of arc = 210/360 × 2 × π × 13
Length of arc = 15.167π feet
rounding up to 2 decimal places, it becomes
15.17π feet
