Pipe cross section

The pipe has an outside diameter 1100 mm and the pipe wall is 100 mm thick. Calculate the cross section of this pipe.

Correct answer:

S =  6361.7251 cm2

Step-by-step explanation:

D=1100 mm r=D/2=1100/2=550 mm T=100 mm r1=rT=550100=450 mm S1=π r12=3.1416 4502636172.5124 mm2 S=S1/102=636172.5124/102=6361.7251 cm2
