Q. A cylinder has a height of

8

feet and a radius of

4

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, $r = 4$ feet and $h = 8$ feet. $\newline$ Volume = $3.14 \times 4^2 \times 8$
Calculate radius square: Step $2$ : Calculate the square of the radius. $\newline$ $4^2 = 16$
Find volume: Step $3$ : Multiply the results to find the volume. $\newline$ Volume = $3.14 \times 16 \times 8$ $\newline$ Volume = $3.14 \times 128$ $\newline$ Volume = $401.92$ cubic feet
