Answer:

Arc length of the semicircle is 12.57 cm.

Explanation:

From the given picture,

Measure of diameter = 8 units

Radius of the semicircle =
$\frac{\text{Diameter}}{2}$

=
(8)/(2)

= 4 units

Since, circumference of a semicircle is given by the expression,

C = πr

Here, r = radius of the semicircle

Circumference of the given semicircle = π(4)

= 4π

= 12.57 cm

Therefore, arc length of the semicircle is 12.57 cm.
