Get the distance between the origin and HitPoint for Raycast?

Hey guys, I need a raycast to check the distance between two points for an “if” statement. So as an example:

if("Distance of Ray" > 10)
	{
	//Do something
	}
else
	{
	//Do something else
	}

Thanks in advance!

To check the distance between the two points you can use: Vector3.Distance(origin, hitpoint).
Here is the script reference on it: Vector3.Distance
