Answer:

The length of arc AB is 5.59 cm

Explanation:

Here, we want to find the length of the arc AB

To find this, we use the formula for the length of an arc

Mathematically, we have this as;

AB = theta/360 * 2 * pi * r

theta is central angle = 40

r is radius = 8

Substituting these values;

AB = 40/360 * 2 * 3.142 * 8

AB = 5.59 cm
