Use formula for volume of cylinder, V=pi x radius squared x depth. Where Pi=3.14, radius= 13.5 feet,and depth= 4 feet. The answer will be in cubic feet. I calculate it to be 2299.06 cubic feet but I'm half asleep. Use various conversion factors to get other volume measures.
For a round above ground pool, the calculation is:
Diameter x Diameter x Depth X 5.9 = Number of Gallons
Please note that the depth is the ACTUAL water depth NOT the height of the pool wall (the water is usually around 6 inchs lower than the wall height).
For your example:
For a 27-foot round pool with a actual water depth of 3.5 ft: 27x27x3.5x5.9 = 15,054 or around 15,000 gallons.
Hope this helps ...

About 49,246.3 liters of water.
Around 22,870 liters of water.
A 22-foot round pool that is 4 feet deep holds about 43,238.5 liters of water.
About 39,397 liters.
About 129,715 liters.
About 45,025 liters.
Assuming the pool is circular, and that you fill the pool to the brim, the pool will contain about 2028 liters of water. However, if you want to leave 4 inches for the water to have some room to splash around, that'll cut that number down to 1859 liters.
right at 1809,000 liters
About 11,708 gallons.
