What is the radius of 19?

The term "radius" typically refers to the distance from the center to the edge of a circle or sphere. If you are asking for the radius of a circle with an area of 19 square units, you can use the formula ( A = \pi r^2 ) to find the radius ( r ). Solving for ( r ), you get ( r = \sqrt{\frac{19}{\pi}} ), which is approximately 2.47 units. If you meant something else by "radius of 19," please provide more context.
