Question

What is the ratio for the volumes of two similar cylinders, given that the ratio of their heights and radii is 2:3?

Answer 1

It's important to know that volumes are three-dimensional magnitudes, which means they are cubic powers. In this case, we just have to elevate the given ratio to the third power.

`((2)/(3))^3=(8)/(27)`

Hence, the answer is A.
