Question

the radius of a cylindrical construction pipe is 2 ft. if the pipe is 16 ft long, what is its volume? use the value 3.14 for π, and round your answer to the nearest whole number. be sure to include the correct unit in your answer.

Explanation:

Step1: Recall cylinder volume formula

$V = \pi r^2 h$

Step2: Substitute given values

$V = 3.14 \times (2)^2 \times 16$

Step3: Calculate squared radius

$(2)^2 = 4$

Step4: Multiply values sequentially

$3.14 \times 4 = 12.56$
$12.56 \times 16 = 200.96$

Step5: Round to nearest whole number

$200.96 \approx 201$

Step6: Assign correct unit

Volume unit is cubic feet ($ft^3$)

Answer:

201 ft³
