C = pi * d
C = 3.14 * 18
C = 56.52 feet
54 inches = 4.5 feet
56.52 / 4.5 = 12.56 = 13 strands

Circumfrance= piXdiameter
C=piX18
56.548
FEET INTO INCHES
56.548X(12)=678.576
DIVIDE 678.576 BY 54
678.576 DIVIDED BY 54= 12.566 ROUNDED TO 12.56
12.56 strands of light are needed to surround the patio edge.
