Help me please I really need help every app i use gives me the wrong answer

Answer 1

We are asked to determine the volume of a cylinder. To do that we will use the following formula:

`V=\pi r^2h`

Where:

`\begin{gathered} V=\text{ volume} \\ r=\text{ radius} \\ h=\text{ height} \end{gathered}`

Now, we plug in the values:

`V=(3.14)(4cm)^2(8cm)`

Now, we solve the operations:

`V=401.92cm^3`

Therefore, the volume is 401.92 cubic centimeters.
