Question

the question is: what is the volume of the cylinder to the nearest tenth? I have 141.3 but that is not correct.

Answer 1

ANSWER

$V=141.4\operatorname{cm}$

EXPLANATION

The volume of a cylinder is given as:

$V=\pi r^2h$

where r = radius

h = height

From the question:

$\begin{gathered} r=3\operatorname{cm} \\ h=5\operatorname{cm} \end{gathered}$

Therefore, its volume is:

$\begin{gathered} V=\pi\cdot3^2\cdot5 \\ V=141.4\operatorname{cm}^3 \end{gathered}$

That is the answer to the nearest tenth.
