Find the length of each arc. Round your answers to the nearest tenth. r = 40 =24use 3.14 for π

liraira [26]

Answer:

1.7 units

Explanation:

The length of an arc is calculated using the formula below:

$l=\frac{\theta}{360\degree}\times2\pi r$

Substitute the given values of θ and r:

$\begin{gathered} l=\frac{24\degree}{360\degree}\times2\times3.14\times4 \\ =1.674 \\ \approx1.7\text{ units (to the nearest tenth)} \end{gathered}$

The length of the arc is 1.7 units.
