Answer:
54.22 mm
Step-by-step explanation:
Find the circumference of the circle and then divide it by 2.
We start with the formula for the circumference for the circle:
C = 2πr
To find r, divide 22 by 2:
22/2=11
Now find the cicumference:
C = 2πr = 2(3.14)(11) = 108.46 mm
NOW, to find the perimeter of the semicircle, divide the circumference by 2:
108.46/2 = 54.22 mm
