Answer:

P = 15.71 cm

Step-by-step explanation:

Given that,

The diameter of the semicircle, d = 10 cm

Radius, r = 5 cm

The perimeter of the semicircle is given by :

[tex]P=\dfrac{\text{The perimeter of the circle}}{2}\\\\=\dfrac{2\pi r}{2}\\\\=\pi r\\\\=3.142\times 5\\\\=15.71\ cm[/tex]

So, the perimeter of the semicircle is 15.71 cm.
