Question

The following image represent a potential garden space in a section of a yard. If chicken wire comes in rolls that are 48 inches long, determine the smallest amount of rolls that will be needed to fence the garden

Answer 1

7 rolls

Explanation:

Arc length

l = (130/360) * 2π(6)

l = 13.6135681656

Side lengths

there are (2) 6 ft radii

l = 12

-------------------

total perimeter

12 + 13.6

25.6 feet

----------------

rolls needed

48in = 4ft

25.6 / 4 = 6.4

Round up as full rolls must be bought

7 rolls
