The answer depends on what the 27' refers to: the radius, diameter or circumference of the pool. A pool which is 27' across will cover 572.6 square feet.
If you are asking about a 27' circumference pool, then the answer is 27'
13' x 27' = 351 square feet.
27 x 50 = 1,350 square feet
27 acres = 1,176,120 square feet.
27 acres is 1,176,120 square feet.
27 x 7 = 189 square feet.
A 27 acre parcel contains 1,176,120 square feet.
27' by 11' = 27 x 11 = 297 (square feet).
The length of the swimming pool is 20 feet Check: 20 times 10 = 200 square feet
There are 27 square feet in 2.51 square meters. A meter is 3.28 feet 2.51 x 3.28 x3.28 = 27 square feet
To find the circumference of a round pool, you can use the formula (C = \pi \times d), where (d) is the diameter. Since the diameter of a 27-foot pool is 27 feet, the circumference would be (C = \pi \times 27 \approx 84.82) feet. Thus, the circumference of a 27-foot round pool is approximately 84.82 feet.
For a pool 52 inches deep, we will assume you don't want it filled to the brim. Let's fill it to 4 inches below the top. Then the water depth will be 48 inches, or 4 feet. (If this is a math assignment problem rather than a practical question, and you want to calculate as though you'd fill the pool to the brim, just rework the problem with a height of 4.333 feet instead of 4 feet.) But there is still the question of whether the pool is 27 feet around or 27 feet across. So we'll do it both ways. If your "27 foot round pool" is 27 feet around (circumference): The circumference of a circle is pi x d. So the diameter of this pool is 27' / pi = 27'/3.1416 = 8.6'. The radius of this circle is half the diameter, or 4.3'. The area is pi x r2 = 3.1416 x (4.297')2 = 58 square feet. The volume of water in the pool is the area times the height: 58 square feet x 4 feet = 232 cubic feet. Since 1 cubic foot holds 7.481 gallons, this pool will hold 232 x 7.481 or 1,736 gallons of water (to the nearest gallon). (At 8.34 pounds/gallon, this much water weighs 14,478 pounds.) If your "27 foot round pool" is 27 feet across (in diameter): Then the radius of the round pool is half that, or 13.5'. The area is pi x r2 = 3.1416 x (13.5')2 = 572.56 square feet. The volume of water in the pool is the area times the height: 572.56 square feet x 4 feet = 2290 cubic feet. Since 1 cubic foot holds 7.481 gallons, this pool will hold 2,290 x 7.481 or 17,133 gallons of water (to the nearest gallon). (At 8.34 pounds/gallon, this much water weighs 142,889 pounds.)
