2. Find the volume of the cylinder. Round to the nearest tenth if necessary.

Diameter = 4 mm

Height = 8 mm

A. 131.1 mm³

B. 100.5 mm³

C. 116.9 mm³

D. 230.0 mm³

Answer :

Answer:

Option B is correct.

Step-by-step explanation:

Diagram of given scenario shown below.

Given that,

Diameter of cylinder is [tex]4\ mm[/tex].

Height of cylinder is [tex]8 \ mm[/tex].

So, Radius of cylinder is [tex]= \frac{4}{2}=2\ mm[/tex]

Volume of cylinder = [tex]\pi r^{2} h[/tex] {where, [tex]\pi =\frac{22}{7}=3.14[/tex] , [tex]r[/tex] is the radius

of cylinder and [tex]h[/tex] is height of cylinder}

Substituting the values we get,

Volume of cylinder [tex]=\pi \times (2)^{2}\times 8[/tex]

[tex]=3.14 \times 32\\=100.48\ mm^{3}[/tex]

Therefore, Required volume of Cylinder rounding it to the nearest tenth ≈ [tex]100.5\ mm^{3}[/tex].

Hence, option B is correct.
