Answer 1

Given:

radius of a cylindrical construction pipe is 3 ft

lenghtis 25ft long

Required:

what is it’s volume

Explanation:

volume of cylinder:

$\begin{gathered} V=\pi r^2h \\ \\ here\text{ h is the length of the pipe} \\ \\ V=3.14\times(3)^2\times25 \\ \\ V=3.14\times9\times25 \\ \\ V=707\text{ ft}^3 \end{gathered}$

Required answer:

$V=707\text{ ft}^3$
