Answer 1

Given:

radius of a cylindrical construction pipe is 3 ft

lenghtis 25ft long

Required:

what is it’s volume

Step-by-step explanation:

volume of cylinder:

`\begin{gathered} V=\pi r^2h \\ \\ here\text{ h is the length of the pipe} \\ \\ V=3.14*(3)^2*25 \\ \\ V=3.14*9*25 \\ \\ V=707\text{ ft}^3 \end{gathered}`

Required answer:

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