Give your answer as an expression in terms of .
d cm​


Sagot :

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.
