Perimeter of circle = 2πr
Perimeter of semi circle = 2πr /2
= π r
Diameter = 14cm
Radius = Diameter/2 = 14/2 = 7
Perimeter = πr
= × 7
= 22cm

Step-by-step explanation:
perimetre of semicircle = π r + 2r
because π r is CIRCUMFERENCE and 2r is diameter
Perimeter is sum of all length
so
Perimeter = π r + 2r
= π * 7 + 2* 7
= 7 ( 22/7) +14
=22 + 14
= 36 CM
