How much water was lost 3 inches in a 27 ft round pool?

Answer 1

To calculate the volume of a depth of 3 inches covering a circle with a diameter of 27 feet take the following steps.

1. Halve the diameter to get the radius - half of 27 = 13.5
2. Calculate the square area of the circle = Π (13.5)2

   (13.5)2 = 182.25

   The usual value of Π = 3.1416

   3.1416 x 182.25 = 572.5566 square feet.

3. Multiply that by the height of the water to get volume. As the 3 inches is a quarter of a foot we'll use 0.25 as the height.

   572.5566 x 0.25 = 143.13915

4. The volume of the water is 143.13915 cubic feet.

• I cubic foot = 7.48051 US gallons

  Therefore the water is 143.13915 x 7.48051 = 1070.755 US gallons

• I cubic foot = 6.22883 Imperial gallons

  Therefore the water is 143.13915 x 6.22883 = 891.590 Imperial gallons

• I cubic foot = 28.3168 litres

  Therefore the water is 143.13915 x 28.3168 = 4053.249 litres
