Diameter 30533

The open tank has the shape of a cylinder with a diameter of d = 1 m and a height of v = 2 m. How many m² of sheet metal is needed to make the tank?
How many liters of water will fit in this tank?

Correct answer:

S =  7.0686 m2
V =  1570.7963 l

Step-by-step explanation:

d=1 m v=2 m r=d/2=1/2=21=0.5 m  S1=π r2=π 212=3.1416 0.520.7854 m2 S2=π d v=3.1416 1 26.2832 m2  S=S1+S2=0.7854+6.2832=7.0686 m2
V1=S1 v=0.7854 21.5708 m3 V=V1 l=V1 1000  l=1.5708 1000  l=1570.796 l=1570.7963 l
