First, let’s find the circumference. The circumference is calculated by the formula С = 2пr.

Where r is the radius of the circle, n is pi equal to 3.14.

C = 2 * 3.14 * 2.5 cm = 15.7 cm.

Now let’s calculate the length of the arc.

15.7 cm * 0.4 = 6.28 cm.

Answer: The length of the arc is 6.28 cm.
