a 24 inch circle is a 2 ft diameter circle, or a 1 ft radius circle. the area of a circle is pi * r squared, so 1 ft squared is 1 sq ft. Times pi (=3.14159) is 3.14159 sq ft
The circumference equals the diameter times pi; therefore, the circumference of this circle is 24 X pi = 75 feet, to the justified number of significant digits (limited by "24").
The circumference of a circle with a diameter of 10 ft is: 31.42 feet (diameter x Pi = circumference).
Circumference of a circle is pi multiplied by the diameter. If the diameter of the circle is 11 ft, the circumference is: 3.14 x 11 ft = 34.54 ft
The circumference and area of a circle with a 17 ft diameter are:C = 53.4 ftA = 227 ft2
