if 4 foot is the circumference then the diameter is 4/pi = 1.27323954
48First of all, you must have meant cubic feet (volume) not square feet.The area of a 2 ft. diameter pipe is 2*2*Pi/4 = Pi = 3.1416 sq.ft.The volume = area*length = 3.1416*12 = 37.6991cu.ft."Diameter" implies a round pipe.
Circumference = pi*diameter so diameter = circumference/pi = 40/pi = 12.7324 feet (to 4 dp)
I assume that you mean it's 4 ft in diameter, and you want to know the number of Sq Ft in the top. If so, the Area is equal to (Pi) X (Radius squared.) OR Since the Radius of a circle is 1/2 the Diameter ... the answer is [(4/2) X (4/2)] X Pi OR 4 X 3.14159 == 12.56636 Sq Ft
Assuming you mean diameter, the answer is 8 feet.
The surface of a circle is given by the formula d2pi/4, so for our 44 inch diameter table, that gives 484pi square inches, which is aproximately 1520.531 square inches.
The diameter of a 4-foot table is 48 inches, as there are 12 inches in a foot. If the table is round, its diameter would be 48 inches. If it is rectangular or square, the measurement would refer to the length of one side rather than a diameter.

How many gallons will fit into a 24 foot diameter x 4 foot high round swimming pool
21 foot what? Radius, diameter or circimference? Presumably 4 feet deep?
Does "15 foot round" refer to Perimeter, Diameter or Radius.
To determine the size of the tablecloth needed for a 42-inch round table with a 4-inch overhang, you would add twice the overhang to the table's diameter. This means you need to add 8 inches (4 inches on each side) to the 42-inch diameter. Therefore, you would need a tablecloth that is at least 50 inches in diameter to achieve the desired overhang.
A 4' diameter table will have a circumference of ~12.5'. Assuming each person takes up just a little bit above 2', there should be enough room for a maximum of 6 people.

To find the areas of the circular tables, we use the formula for the area of a circle, ( A = \pi r^2 ). The radius of the first table (diameter 6 ft) is 3 ft, giving an area of ( \pi (3^2) = 9\pi ) square feet. The radius of the second table (diameter 8 ft) is 4 ft, giving an area of ( \pi (4^2) = 16\pi ) square feet. The difference in areas is ( 16\pi - 9\pi = 7\pi ), which is approximately 22 square feet when rounded to the nearest square foot.
If that is 4 feet tall and 18 inches in diameter, it would be 16.83 gallons.
A 4-foot round table can typically seat about 4 to 6 people comfortably, depending on the space needed for dining and personal comfort. If the seating is tight, you might fit up to 8 people, but this would likely be a less comfortable arrangement. For optimal comfort, it's best to stick to around 4 to 6.
Along the diameter, exactly 4 of them.
