If the arcs of the same length in two circles subtend angles `65^(@)` and `110^(@)` at the center, then the ratio of their radii.

Explanation

To solve the problem, we need to find the ratio of the radii of two circles given that the arcs of the same length subtend angles of 65° and 110° at the center of each circle.

### Step-by-Step Solution:

1. **Understanding the Relationship**:
The length of an arc \( L \) in a circle is given by the formula:
\[
L = R \cdot \theta
