Soil with a unit weight of 17.35 kN/m³ is loaded on the ground sufrace by a uniformly distributed load of 185 kN/m² over a circular area 5 m in diameter. Geotechnical investigation indicates that a ground water table is located 4.2 m below the ground surface. Required Determine the total vertical pressure at a depth of 7.5 m under the edge of the circular area. Provide answer in kN/m², to the nearest 100th.
