The circle will thus have a circumference of 56 ft 6 in or 678 inches. The circumference of a circle is
where r is the radius and π is approximately 3.1416. Thus you have
and thus
12 × 9 = 108 so the radius of the circle is very close to 9 ft. We are curious about what you are making. Can you tell us? Penny
