Diameter = 18/pi = 5.73 feet, approx.
fifty-six The circumference of an 18-foot diameter circular swimming pool is: 56.55 feet
If that is 4 feet tall and 18 inches in diameter, it would be 16.83 gallons.
18 ft diameter is assumed. Area = Pi/4 x 182 = Pi x 81 = 254.469 ft2
216 square feet (12 x 18 = 216)
A circle with a diameter of 18 feet has an area of 254.5 square feet.
A circle with a diameter of 18 feet has a perimeter of 56.5 feet.
A linear foot is the same as a foot. So, an 18-foot diameter circle would measure 18 linear feet in diameter!
Diameter = 18/pi = 5.73 feet, approx.
Area = 254 square feet.
It would be about 56.5 feet.
36 feet across, 18 feet from centre to circumference, or 113.1 ft (approx) around the circle.
fifty-six The circumference of an 18-foot diameter circular swimming pool is: 56.55 feet
If that is 4 feet tall and 18 inches in diameter, it would be 16.83 gallons.
Assuming that the pool diamater diminishes 1 foot for each foot of height, and the pool is filled to the top, the total capacity would be about 6439 gallons.
18 ft diameter is assumed. Area = Pi/4 x 182 = Pi x 81 = 254.469 ft2
216 square feet (12 x 18 = 216)
