Answer: 28.26 meters
Step-by-step explanation:
Hi, to answer this question we have to find the perimeter of the semicircle.
P = (2 π r ) /2 (perimeter of a circle divided by 2)
The length of AB is the diameter of the circle (18 meters)
Since
Diameter (d) = 2 radius (r)
Replacing with the value given:
18 =2r
18/2=r
9 =r
Back on the perimeter formula
P = (2 π r ) /2
Replacing with the values given
P = (2 x 3.14 x 9) /2
P = 28.26 meters
