We know that water has a density of 1 kg/L therefore: 1272.3450247 liter = 1272.3450247 kilograms

Now we know the weight of the water the tank holds when full, just divide that by the area (not the volume) of the tank to get the pressure: Pi * (30/2)² = 706.858347 cm² 1272.3450247 / 706.858347 = 1.8 kg/cm²

Now we know the pressure on the bottom of the tank, just need to convert that to the unit you need, bar: 1.8 kgf/cm² = 1.765197 bar

There's no need for calculation of volume. The common equation pressure = density * height * gravitational constant (g) is all you need....

btw density = 980 kg/m3 and not 1000 kg/m3

pressure = 18m * 980 kg/m3 * 9.81 m/s2 pressure = 173048 kg/(ms2) = 173048 Pa pressure = 1.73048 bar (gauge).... or 2.173048 bar absolute..
