Answer:

[tex]\boxed{P = 56.55751919 cm}[/tex]

Step-by-step explanation:

Perimeter of semicircle = [tex]\frac{2\pi r}{2} + 2r[/tex]

Where r = 11 cm

=> P = [tex]\frac{2(3.142)(11)}{2} + 2(11)[/tex]

=> P = [tex]34.55 + 22[/tex]

=> P = 56.55751919 cm

Answer:

56.562 cm

Solution,

Radius(R)= 11 cm

Perimeter of semi-circle:

[tex]\pi \: r + 2r [/tex]

[tex] = 3.142 \times 11 + 2 \times 11[/tex]

[tex] = 34.562 + 22[/tex]

[tex]56.562 \: cm[/tex]

Hope this helps...

Good luck on your assignment..
