the radius of a cylindrical construction pipe is 3 ft. if the pipe is 30 ft long, what is its volume? use…

Explanation:

Step1: Recall volume formula

The volume formula for a cylinder is $V = \pi r^{2}h$, where $r$ is the radius and $h$ is the height (or length in this case).

Step2: Substitute given values

Given $r = 3$ ft and $h=30$ ft, and $\pi = 3.14$. Substitute into the formula: $V=3.14\times3^{2}\times30$. First, calculate $3^{2}=9$. Then the expression becomes $V = 3.14\times9\times30$. $3.14\times9 = 28.26$, so $V=28.26\times30$. $28.26\times30 = 847.8$.

Step3: Round the result

Rounding $847.8$ to the nearest whole number gives $848$.

Answer:

$848$ cubic - feet
