Question

A trash can is in the shape of a cylinder. It has a radius of 2 feet and a height of 5 feet. What is the volume of the trash can? Round to the nearest tenth. Use 3.14 for es028-1.jpg.

cubic feet

Answer 1

To calculate 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 \( r = 2 \) feet
- Height \( h = 5 \) feet
- Using \( \pi \approx 3.14 \)

Now, substitute the values into the formula:

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

First, calculate \( r^2 \):

\[
2^2 = 4
\]

Now substitute that back into the equation:

\[
V = 3.14 \times 4 \times 5
\]

Next, multiply \( 4 \times 5 \):

\[
4 \times 5 = 20
\]

Now multiply by \( 3.14 \):

\[
V = 3.14 \times 20 = 62.8
\]

So, the volume of the trash can is:

\[
\boxed{62.8} \text{ cubic feet}
\]
