Question

Find the volume of the cylinder, in cubic centimeters. Use 3.14 for pi. Round your answer to the nearest tenth. Height is 5 cm and the radius is 3 cm.

Answer 1

To find the volume of a cylinder, you can use the formula:

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

where \( V \) is the volume, \( r \) is the radius, and \( h \) is the height.

Given:
- Radius \( r = 3 \) cm
- Height \( h = 5 \) cm
- Use \( \pi \approx 3.14 \)

Now, substitute the values into the formula:

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

Calculate \( (3)^2 \):

\[
(3)^2 = 9
\]

Now substitute this value back into the equation:

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

Calculate \( 9 \times 5 \):

\[
9 \times 5 = 45
\]

Now substitute this back into the equation:

\[
V = 3.14 \times 45
\]

Now do the multiplication:

\[
V = 141.3
\]

Therefore, the volume of the cylinder is approximately:

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