If the lines `3x-4y+4=0` and `6x-8y-7=0` are tangents to a circle, then find the radius of the circle.

Explanation

To find the radius of the circle given that the lines \(3x - 4y + 4 = 0\) and \(6x - 8y - 7 = 0\) are tangents to the circle, we can follow these steps:

### Step 1: Identify the equations of the lines
The two given lines are:
1. \(3x - 4y + 4 = 0\) (Line 1)
2. \(6x - 8y - 7 = 0\) (Line 2)

### Step 2: Check if the lines are parallel
