Answer: a. [tex]37,680\ mm^3[/tex]
Step-by-step explanation:
We know that the volume of a cylinder is given by :-
[tex]V=\pi r^2 h[/tex], where r is radius and h is height of the cylinder.
Given: The diameter of cylinder = 40 mm
The radius of cylinder =[tex]r=\dfrac{40}{2}=20\ mm[/tex]
The height of cylinder = 30 mm
Then , the volume of the cylinder will be :-
[tex]V=(3.14) (20)^2 (30)=37680\ mm^3[/tex]
Hence, the volume of the cylinder = [tex]V=37680\ mm^3[/tex]
