you can find the circumference of the circle with the circumference equals 2pir. circumference=2pi9 circumference=18pi circumference=56.55 feet you can then turn the feet into inches by multiplying by 12 (56.55 feet)x(12inches/foot)=678.58 inches then divide 678.58 inches by 54 inches to find how many light strands are needed. (678.58 inches)/(54 inches/strand)=12.57 strands
