For this case we have that by definition, the volume of a cylinder is given by:[tex]V = \pi * r ^ 2 * h[/tex]
Where:
r: It is the radius of the cylinder
h: It is the height of the cylinder
According to the statement we have to:
[tex]r = \frac {40} {2} = 20 \ mm\\h = 3 \ mm[/tex]
Substituting we have:
[tex]V = \pi * 20 ^ 2 * 3\\V = \pi * 400 * 3\\V = 1200 \pi[/tex]
Thus, the volume of the cylinder is: [tex]V = 1200 \pi \ mm ^ 3[/tex]
Answer:
[tex]V = 1200 \pi \ mm ^ 3[/tex]
