Here's how to calculate the force on the circular wall:

1. Calculate the area of the wall:

* Radius (r) = Diameter / 2 = 3 m / 2 = 1.5 m

* Area (A) = π * r² = π * (1.5 m)² ≈ 7.07 m²

2. Calculate the force:

* Pressure (P) = 1100 kPa = 1100,000 Pa (Pascals)

* Force (F) = Pressure (P) * Area (A)

* F = 1100,000 Pa * 7.07 m² ≈ 7,777,000 N (Newtons)

Therefore, the force produced on the circular wall is approximately 7,777,000 Newtons.
