- Radius[ <Conic> ]
- Returns the radius of a conic.

**Example:**- Returns the radius of a circle c (e.g. c:(x - 1)² + (y - 1)² = 9)
`Radius[c]`

yields*a = 3*. - Returns the radius of a circle formula
`Radius[(x - 2)² + (y - 2)² = 16]`

yields*a = 4*.

- Returns the radius of a circle c (e.g. c:(x - 1)² + (y - 1)² = 9)
