Calculate 423

Calculate the volume and surface area of ​​a cylinder if its height is 40 dm and the diameter of the base is 3 m.

Correct answer:

V =  28274.3 dm3
S =  5183.6 dm2

Step-by-step explanation:

h=40 dm D=3 m dm=3 10  dm=30 dm  r=D/2=30/2=15 dm  S1=π r2=3.1416 152706.8583 dm2  V=S1 h=706.8583 40=28274.3 dm3
S2=π D h=3.1416 30 403769.9112 dm2  S=2 S1+S2=2 706.8583+3769.9112=5183.6 dm2
