The circumferential stress in a cylindrical pressure vessel can be calculated using the formula:

σc = PD / (2t)

Where:
σc = circumferential stress
P = internal pressure
D = diameter of the vessel
t = wall thickness of the vessel

Plugging in the given values:

σc = (4.5 MPa) * (400 mm) / (2 * 20 mm)

Converting the units to Pa:

σc = (4.5 * 10^6 Pa) * (0.4 m) / (2 * 0.02 m)

Simplifying:

σc = 9 * 10^6 Pa

So, the circumferential stress in the cylindrical pressure vessel is 9 MPa.
