Answer: the length of the arc is 15.17π feet

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 = 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
