Water reservoir

What is the weight of a metal reservoir - cylinder with a diameter of 2 m and a length 8 m, if 1 m2 of sheet metal weighs 100 kg?

Correct answer:

m =  5026.5482 kg

Step-by-step explanation:

D=2 m l=8 m  r=D/2=2/2=1 m  S1=p r2=p 12=0 m2 S2=π D l=3.1416 2 850.2655 m2  S=2 S1+S2=2 0+50.265550.2655 m2 h=100 kg/m2  m=h S=100 50.2655=5026.5482 kg
