Answer:
Length of the bold arc = 72.63 ft
Step-by-step explanation:
Length of the arc = 
Here, θ = angle subtended by the arc at the center
r = Radius of the circle
Since, angle subtended by the bold arc at the center = 360 - 73
= 287°
And radius of the circle 'r' = 14.5 ft
By substituting these values in the formula,
Length of the bold arc = 
= 72.632
≈ 72.63 ft
Therefore, length of the bold arc = 72.63 ft
