how many linear feet in a 20 foot diameter
704.5 gallons (approx).
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).
74.4 ft2
Along the diameter, exactly 4 of them.
5.5
The radius of a circle is half the length of the diameter. Therefore, if the diameter is 1 foot, the radius would be 0.5 feet. This is because the radius is the distance from the center of the circle to any point on the circle's circumference, while the diameter is the distance across the circle passing through the center.
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).
The formula is pi times diameter. If the diameter is 1 foot, times 3.14, the circumference will be 3.14 feet.
The area of a circle is PI times the radius of the circle squared. The radius of a one foot diameter circle it 1/2 or .5 feet. .5 squared is .25 PI is 3.1416 3.1416 times .25 = .79 square feet So, there are about .8 square feet in a 1 foot diameter circle.
There are 10 linear feet in a 10 foot diameter circle.
The circumference of a circle with a 31 foot diameter is 97.4 feet, approx.
A circle with a 7 foot diameter has a circumference of 22 feet (approx).
If it is 1 foot diameter by 4 feet long, then it's pi*(1/2 ft)2 * (4 ft) = (pi) ft3. If it's 4 feet diameter by 1 foot tall, then it's pi*(2 ft)2 * (1 ft) = (4*pi) ft3.

None. A 12 foot diameter is the length across a circle: it is a linear distance, not an area.
