perimeter = 25.71 km


Step-by-step explanation:

the perimeter (P ) or circumference of a circle is

P = 2πr = πd


where r is the radius and d is the diameter
here it is a semicircle, that is half the circle

⇒ 1/2 × 2πr = πr is the perimeter

here d = 10 ⇒ r = 10/2 = 5


the perimeter of this semicircle includes the diameter

⇒ P = (π × 5) + 10

= (3.142 × 5) + 10

= 15.71 + 10

= 25.71 km
