the arc length is calculated by the formula
$\displaystyle\bf C=(2\pi r)/(360) \cdot\alpha$ then
$\displaystyle\bf C=(2\cdot 8 \pi )/(360) \cdot180=8\pi=3,14\cdot8=25.12$ or it can be calculated using the circumference of the circle since we have a semicircle the circumference 2πr must be divided by 2 С=2πr:2=πr =8π=25,12
