If the base is 18 cm, then the diameter of the semi-circle is 18. The perimeter is half a circle plus 18, or (1/2)pi(18) + 18
9pi + 18 cm or approx. 46.274 cm
Be careful, you need to include the base segment as part of your perimeter. The other answers are only including the length of the half-circle.

Perimeter of a circle is 2*(pie)* r where r is the radius
so devide 18 by 2 to get the radius
it will be : 2*3.142*9
then devide ur answer with 2 to get the semi-circle permeter

Length of a circle’s circumference is 2*(pi)*r.
If you want the circumference of a semi circle, it would be 1/2 of that number, or (pi)*r.
