Answer:
perimeter = 15.42 cm
Explanation:
Semi-circle is defined as half a circle.
The formula used to compute the perimeter of the semi circle is:
perimeter = πr + 2r
where:
π is a constant = 3.14
r is the radius = 3 cm
Substitute with the givens in the above formula to get the perimeter as follows:
perimeter = π(3) + 2(3)
perimeter = 3π + 6
perimeter = 3(3.14) + 6
perimeter = 15.42 cm
Hope this helps :)
