Q. A cylinder has a height of

19

feet and a radius of

19

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: Step $1$ : Identify the formula for the volume of a cylinder and plug in the given values. $\newline$ Volume = $\pi \times r^2 \times h$ $\newline$ Here, $r = 19$ feet and $h = 19$ feet. $\newline$ Volume = $3.14 \times 19^2 \times 19$
Calculate radius square: Step $2$ : Calculate the square of the radius. $\newline$ $19^2 = 361$
Find volume: Step $3$ : Multiply the results to find the volume. $\newline$ Volume = $3.14 \times 361 \times 19$ $\newline$ Volume = $3.14 \times 6859$ $\newline$ Volume = $21529.66$ cubic feet
