Question

The volume of two cylinders have a ratio of 27:125. What is the ratio of their radii?

Answer 1

`V=\pi r^2h`
`\begin{gathered} (27)/(125)=(r^3)/(R^3) \\ \\ (27)/(125)=((r)/(R))^3 \\ \\ \sqrt[3]{(27)/(125)}=(r)/(R) \\ \\ (3)/(5)=(r)/(R) \end{gathered}`

The final answer

Option D

`27:125=3:5`
