The ratio between the curved surface area and the total surface area of a right circular cylinder is 1:2. Find the ratio between the height and radius of the cylinder.

Explanation

To solve the problem, we need to find the ratio between the height (h) and the radius (r) of a right circular cylinder given that the ratio of the curved surface area (CSA) to the total surface area (TSA) is 1:2.

### Step-by-Step Solution:

1. **Understand the Formulas:**
- The formula for the curved surface area (CSA) of a right circular cylinder is:
\[
\text{CSA} = 2\pi rh
