Question

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 1

Answer:

Option B is correct.

Step-by-step explanation:

Diagram of given scenario shown below.

Given that,

Diameter of cylinder is $4\ mm$.

Height of cylinder is $8 \ mm$.

So, Radius of cylinder is $= \frac{4}{2}=2\ mm$

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

                                                               of cylinder and $h$ is height of cylinder}

Substituting the values we get,

Volume of cylinder $=\pi \times (2)^{2}\times 8$

                                $=3.14 \times 32\\=100.48\ mm^{3}$

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

Hence, option B is correct.
