Hey... I think this can be ur answer!!
___________________________
Perimeter of semicircle = pie r
So,
Perimeter = 22/7 * 14 = 22*2 = 44cm...
SO when circle is cut into half than diameter is also included
Now,
Final perimeter of semicircle = 28 + 44 = 72cm

Hope it helps you dear ☺️☺️☺️

but formula to find perimeter of semicircle is pie r

Perimeter of semicircle = r(pi + 2)
[Where r represents the radius]
So,
--> r(2 + pi )
= 14(2 + 22/7)
= 28 + 22×14/7
= 28 + 44 = 72 cm.
Hope this is ur required answer

but.. when the circle is cut through half
ok
the diameter also bound the semicircle..
so for its Perimeter.. diameter is also taken
yeah got it....
thx
bro
welcome..
hmm bb
bbye
Similar questions
If the radius is 14 cm, then the diameter is 28 cm.
Then half the circumference of the circle would be ½ (2πr) =
½ * 2 * 3.14 * 14 = 43.96
The entire perimeter of the semicircle would be 28 + 43.96 = 71.96 cm
