Answer 1

The volume \( V \) of a cylinder is calculated using the formula:

\[
V = \pi r^2 h
\]

where:
- \( r \) is the radius,
- \( h \) is the height,
- \( \pi \) is approximately 3.14.

Given:
- \( r = 3 \) cm,
- \( h = 5 \) cm.

Now, substituting the values into the formula:

\[
V = 3.14 \times (3)^2 \times 5
\]

Calculating \( (3)^2 \):

\[
(3)^2 = 9
\]

Now plug it back into the volume formula:

\[
V = 3.14 \times 9 \times 5
\]

Calculating \( 9 \times 5 \):

\[
9 \times 5 = 45
\]

Now multiply by \( 3.14 \):

\[
V = 3.14 \times 45 = 141.3
\]

Rounding to the nearest tenth, the volume of the cylinder is

\[
\boxed{141.3} \text{ cubic centimeters.}
\]
