Find the length of each bolded arc. Round to the nearest hundredth.

Nezavi [6.7K]

Answer:

Length of the bold arc = 72.63 ft

Step-by-step explanation:

Length of the arc = $\frac{\theta}{360}(2\pi r)$

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 = $\frac{287}{360}\times (2\pi)(14.5)$

= 72.632

≈ 72.63 ft

Therefore, length of the bold arc = 72.63 ft
