How many cubic meters of water in a swimming pool that is 24 feet round and 5 feet deep?

Answer 1

First the answer should be in meters so it is helpful to convert all the feet measurements into meters.

24 ft = 7.315 m

5 ft = 1.524 m

The way I read the question is that 24 ft (7.315 m) is the circumference of the pool. From this I make the assumption that the pool is a round pool. Thus we can model it as a cylinder. The formula for the volume of a cylinder is:

V = PI * r * r * h

Which means you take the math constant PI (approx. 3.14) multiply it by the radius of the circular face and again multiply it by the radius then multiply it by the height (or depth in the question).

The formula to find the circumference is:

C = 2 * PI * r

To get the radius from the circumference just divide the circumference by (2 * PI).

r = C / (2 * PI)

Plugging in the numbers we get

V = 314 * (7.315 / (2 * 3.14)) * (7.315 / (2 * 3.14)) * 1.524

Calculating this out you get:

V = 6.49 m^3 (meters cubed)

Answer 2

It is not possible to answer the question because the units for 5.5 are not given. Furthermore, a volume usually requires three measurements, you have provided only two.
