There is a misprint in this question the stress should be 20000 not 200.
Then the answer will be 10cm.
Then the answer will be 10cm.

Pressure inside the cylinder, P = Ïgh = 1000 * 10 * 100 = 106 Pa,
= 130.3 MPa
= 130.3 MPa

Hoop stress, s = pd/2t.
p=ρgh=1000 * 10 * 200.
t = 1000 * 10 * 200 * 1/2 * 200 * 1000000.
t = .5 m = 50mm.
p=ρgh=1000 * 10 * 200.
t = 1000 * 10 * 200 * 1/2 * 200 * 1000000.
t = .5 m = 50mm.
