please help me with  this  problem it is Soil Mechanics I know it solved with Terzaghi’s Analysis but he asked for maximum height of water to which the tank may be filled

A circular water tank with a diameter of 30m is to be constructed on a
thick layer of silt. The founding depth of the footing is 2m from the ground
surface. The silt layer has an undrained cohesion of 24kPa and unit
weight of 18kN/m. Assuming a factor of safety of 3.0, recommend the
maximum height of water to which the tank may be filled without causing
failure in the silt layer.
