The circumference of a 128-foot diameter circle is: 402.12 feet.
The circumference of a six-foot diameter circle is: 18.85 feet.
The circumference of a 4 foot circle is: 12.57 feet(diameter x pi = circumference).
The circumference of a 8 foot diameter circle is about 25.13 feet.
The circumference of a 19 foot diameter circle is: 59.7 feet.
The circumference of circle with 60-foot diameter is: 188 feet.
Remember the circle eq'n C = pi d Algebraically rearrange d = C/pi Hence C = 12 pi = 3.141592.... ~ 3.1416 Substitute d = 12 / 3.1416 d = 3.8197,,,. ft. The answer!!!!!
The area of a circle with a 12-foot circumference is about 11.46 square feet.
