The circumference of a 128-foot diameter circle is: 402.12 feet.
The circumference of a six-foot diameter circle is: 18.85 feet.
It is 12.6 ft, approx.
The answer depends on whether the 4 foot measure is the radius or the circumference.
You should clarify whether "1-foot circle" refers to a circle with a radius of 1 foot, a diameter of 1 foot, or a circumference of 1 foot. The circumference of a circle is equal to the diameter times pi (approximately 3.14).
A circle with a 4-foot diameter has a circumference of about 12.57 feet.
The circumference of a circle with a 4-foot radius is about 25.13 feet. (C = r x 2 x Pi)
The circumference of 5 foot circle is: 15.7
The circumference of a 4 foot diameter circle may be obtained by multiplying the diameter by pi, which is 3.1416 4 X 3.1416 = 13 (rounded to the nearest whole number)
The circumference of a 160-foot circle is: 503 feet.
The circumference of a 4 foot diameter circle may be obtained by multiplying the diameter by pi, which is 3.1416 4 X 3.1416 = 13 (rounded to the nearest whole number)
The circumference of an 8-foot circle is: 25.13 feet.
The circumference of a 30-foot diameter circle is: 94.248 feet.
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 19 foot diameter circle is: 59.7 feet.
The circumference of a 8 foot diameter circle is about 25.13 feet.
