Malia is placing a barrier around the edge of a circular path with a diameter of 13 meters. the barriers are in lengths of 2.5 meters. what is the best approximation of how many pieces of barrier malia will need? use 3.14 to approximate for π . a. 5 b. 17 c. 33 d. 53

So you need to find the perimeter (circumference) of the circle
Circumference= 2πr
Radius= 13/2
C=2(3.14)(13/2)
C= (6.28)(6.5)
C= 40.82 meters of the perimeter

Find how many 2.5 meter lengths:
Total perimeter ÷ length of pieces
=40.82/2.5
=16.32 pieces, but since she needs a partial piece (0.32), you have to round up to 17 pieces needed

Hope this helps!! :)
