Q. A cylinder has a height of

7

feet and a radius of

2

feet. What is its volume? Use

\pi \approx 3.14

and round your answer to the nearest hundredth.

\newline

\_\_\_\_\_

cubic feet

Identify formula and values: First, identify the formula for the volume of a cylinder and plug in the given values. The formula is $\text{Volume} = \pi \cdot r^2 \cdot h$ . Here, $r = 2$ feet and $h = 7$ feet.
Calculate volume: Next, calculate the square of the radius $r^2$ and then multiply by the height $h$ and $\pi$ .
