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.
