Question

Please help this is for my study guide thanks! (what is the radius)

Answer 1

We are given the following details

To find the radius, we will make the radius, the subject of the formula from the equation:

`\begin{gathered} r^2=(V)/(\pi h) \\ \\ r=\sqrt[]{(V)/(\pi h)} \end{gathered}`

Substituting the values, we will obtain

`\begin{gathered} r=\sqrt[]{(4019.2)/(3.14*20)}=\sqrt[]{64} \\ \\ r=\sqrt[]{64} \\ \\ r=8 \end{gathered}`

The radius of the cylinder 8.00
