Step-by-step explanation:
Given :-
A semicircle is given with radius of 3cm .
And we need to find the perimeter of the semicircle . We know the perimeter as ,
[tex]:\implies[/tex] Perimeter = πr
[tex]:\implies[/tex] Perimeter = 3cm × π
[tex]:\implies[/tex] Perimeter = 3π cm .
Now there is the diameter of circle is 6cm . Hence totally the perimeter is ,
[tex]:\implies[/tex] Perimeter = 3π + 6 cm
We were supposed to give answers in terms of π .
Hence the perimeter is ( 3π + 6 ) cm
