Answer:
P = 75.40 cm
Step-by-step explanation:
Given that,
The diameter of the semicircle, d = 48 cm
Radius, r = 24 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 24\\\\=75.40\ cm[/tex]
So, the perimeter of the semicircle is 75.40 cm.
Given :
Diameter of the semi-circle is, d = 48 cm.
To Find :
The perimeter of this semi-circle.
Solution :
We know, perimeter of semi-circle is given by :
P = πr
We know, r = D/2
r = 48/2 cm
r = 24 cm
Putting value of r in equation 1) we get :
P = π × 24 cm
P = 75.4 cm
Hence, this is the required solution.
