A cylinder has a base radius of 9 feet and a height of 4 feet. What is its volume in cubic feet, to the nearest tenths place?

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 of the base, and $h$ is the height of the cylinder.

Given:

• Radius ($r$) = 9 feet
• Height ($h$) = 4 feet

Step-by-step calculation:

1. Square the radius: $r^2 = 9^2 = 81$

2. Multiply the squared radius by the height: $81 \times 4 = 324$

3. Multiply the result by $\pi$: $V = \pi \times 324$

Using the approximate value of $\pi$ (3.14159):

$V \approx 3.14159 \times 324 \approx 1017.8766$

4. Round the result to the nearest tenths place: $V \approx 1017.9$

Therefore, the volume of the cylinder is approximately 1017.9 cubic feet.
