The best way to do this is take two vectors (1. world coordinate 2. vehicle position coordinate) and find the Euclidean distance.

In C# this would look like:

Vector3 worldCoordinate = new Vector3(0,0,0);
Vector3 vehiclePosition = Game.PlayerPed.CurrentVehicle.Position;

float distance = worldCoordinate.DistanceSquared(vehiclePosition);

then you can use this distance as the radius.

if(distance < 3f)
{
    // do something
}

In Lua, I’m not sure. I know that there are natives like Vdist2() and GetDistanceBetweenCoords() but doing it without a native is faster. Something like:

if (Vdist2(posX, posY, posZ, carX, carY, carZ) < 3) then
    -- do something
end

but faster (from the natives documentation Native Reference - Cfx.re Docs)

dist = #(vector3(0.0, 0.0, 0.0) - vector3(5.0, 5.0, 5.0))
