Answer is in picture and explanation below.

Step-by-step explanation:

Continuing from the picture,

Area of Metal base = Area of Bigger Circle - Area of Hollow Circle

$1156\pi {mm}^{2} - 225\pi {mm}^{2} \\ = 931\pi {mm}^{2}$

Volume of Cylinder = Area of Metal base x Height (Length in this case)

$931\pi {mm}^{2} \times 40 \\ = 37240\pi {mm}^{3}$
