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
Radius = 1/2 of the diameter = 1/2 foot = 6 inches

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.
74.4 ft2
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.
