Answer:
B. 17
Step-by-step explanation:
We have been given that Maria is placing a barrier around the edge of a circular path with a diameter of 13 meters.
Since we know that circumference of a circle equals , where,
r= Radius of the circle.
Since we have been given the diameter of the circular path, so let us divide our given diameter by 2 to find radius of our circular path.
Let us find the circumference of our circular path.
Since circumference of circular path is 40.82 meters, so to find the number of pieces of barrier we will divide circumference of circular path by length of each barrier.
As the barrier will be used as a whole piece, therefore, Malia needs 17 pieces of barrier and option B is the correct choice.
