Ashley made a circular picture frame with a diameter of 60 cm. She wants to glue string around the outside edge of the frame. String cost $0.32/cm. What is the total cost of a string before taxes?

Circumference = πD

Circumference = 22/7 × 60 = 1320/7 cm

Cost of 1 cm = $0.32

Cost of 1320/7 cm = 32/100 × 1320/7 = $ 60.34

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
