Landscaping Problem

Problem: A drip irrigation system is installed around a circular flower garden that is 4ft in diameter. If the irrigation system costs $5.46 per foot, find the cost to place the irrigation system around the flower garden. Use 3.14 for pie

First thing i did was figure out the distance around which is 12.56 then i times the cost but apparently i am doing it wrong. Can anyone explain this to me?

Re: Landscaping Problem

Sounds like you are doing it correctly to me. You used circumference is pi·diameter = 3.14·4 ft = 12.56 ft, then total cost is (12.56 ft)($5.46/ft) ? $68.58

Is that the result you came to?
