Respuesta :
perimeter of a semicircle is [tex]\frac{2\pi r}{2}+2r=\frac{d\pi}2 +d[/tex]
$d=14$
so, perimeter= $14\cdot\frac{22}7\cdot \frac{1}2+14=22+14=36$ cm
Answer:
Perimeter of semi-circle = 36 cm
Step-by-step explanation:
diameter = d = 14 cm
Perimeter of semicircle = Circumference of semi-circle + diameter
= [tex]\frac{1}{2}\pi d + d[/tex]
= [tex]\frac{1}{2}*\frac{22}{7}*14 +14\\[/tex]
= 22 + 14
= 36 cm
