Perimeter of semicircle = pi*r + 2r
Since d= 14cm
=r = d/2 = 14/2cm
= 7cm.
P= 22/7 × 7cm + 2*7cm
= 22cm + 14cm
= 36cm.

protector have shape of a half circle
radius = 14/2= 7cm
perimeter of half of a circle =πr + diameter
= 22/7×7 + 2×7
=( 22 +14 )cm²
= 36 cm²
radius = 14/2= 7cm
perimeter of half of a circle =πr + diameter
= 22/7×7 + 2×7
=( 22 +14 )cm²
= 36 cm²
