Answer:
<h3>12.56</h3>
Step-by-step explanation:
To get the length of the arc, we are going to use the formula for calculating the circumference of a semicircle.
Circumference of a semi circle = πd/2
Given
Diameter d = 8
π = 3.14
Substitute;
C = 3.14(8)/2
C = 3.14 * 4
C = 12.56
Hence the the length of the arc is 12.56
