Answer:
36 m.
Step-by-step explanation:
circumference of circle = 2 pi r
=2×22/7×7=44 m......(r=d/2)
hence,perimeter of semi circle =44/2+14
=22+14=36 m.
Step-by-step explanation:
Diameter = 14 m
Perimeter of semicircle = πr + 2r
Radius = D/2
Radius = 14/2= 7 m
Perimeter of semicircle= πr + 2r
=22/7 × 7 + 2 × 7
= 22 + 2×7= 22×14=308m
Perimeter of semicircle= 308m
