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 24-foot round pool with a actual water depth of 3.5 ft: 24x24x3.5x5.9 = 11,894 or around 12,000 gallons.
