Answer:

The length of the arc is 3.9 meters to the nearest tenth

Step-by-step explanation:

The formula of the length of an arc of a circle is L = [tex]\frac{x}{360}[/tex] × 2πr , where x is the measure of the arc and r is the radius of the circle

∵ The measure of the arc is 45°

x = 45°

∵ The radius of the circle is 5 meters

r = 5 meters

- Substitute the values of x and r in the formula of the length

   of an arc above

∵ L = [tex]\frac{45}{360}[/tex] × 2π × 5

∴ L = [tex]\frac{1}{8}[/tex] × 10π

∴ L = 3.92699

- Round it to the nearest tenth

L = 3.9 meters

The length of the arc is 3.9 meters to the nearest tenth
