Question

Find the volume of the cylinder: (Use $\pi =3.14$).

• A. $3.190m^3$
• B. $3.920m^3$
• C. $3.925m^3$
• D. $3.820m^3$

Answer 1

Answer: (C)

$3.925m^3$

The radius of the cylinder will be,

$r=\frac{1}{2}m$

$\begin{array}{cc}\text{Volume of the cylinder}& =\pi r^{2}h\\ & =\pi \times {\left(\frac{1}{2}\right)}^2\times 5\\ & =3.14\times \frac{1}{4}\times 5\\ & =3.925m^3\end{array}$

So, option $C$ is correct.
