Answer:
 roughly 12.56 units
Step-by-step explanation:
Since the perimeter of a circle is 2*pi*r, we can divide it by two or multiply by half in order to find the perimeter of a semicircle
half of the diameter is the radius, so 8/2 =4, r=4
Plug in what we know...
C=2*pi*4
Solve
2*3.14*4
25.12
divide by 2
25.12/2=12.56
12.56 units is the perimeter
