help with spawning distance

[hogmason 2]

i use this script

[b]	_dis = 180;
_ang = random 360;
_dx = sin(_ang)*_dis;
_dy = cos(_ang)*_dis;
       _positionToSpawnIn = [((getmarkerpos "taskarea") select 0) + _dx, ((getmarkerpos "taskarea") select 1) + _dy, 0];[/b]
_armourgrp1 = [getmarkerpos "taskarea", east,["T72_TK_EP1", "BRDM2_ATGM_TK_EP1"],[[-3,-3], [3,3]]]  call BIS_fnc_spawnGroup;
[(units _armourgrp1) select 0, "taskarea","spawned","nofollow","random","nowait","delete:",120] execVM "scripts\upsmon.sqf";

to create manned armor all works fine but they all spawn on top of each other cuasing major destruction and tanks flying in the air lol

my question is how can i get them to spawn in say a diamater of 190 from the center of the taskarea marker.

taskarea marker is created by

_Taskarea = createmarker ["taskarea",getpos _task1];
_Taskarea setmarkershape "ELLIPSE";
_Taskarea setmarkersize [190,190];
//"taskarea" setMarkerAlpha 0;  /// unmark to not show

the whole script just in case it helps

Specify more relative positions with greater spacing? You only have 2 listed and 3m might not be enough space?

thanks pelham, that code was given to me so im just working it out ;),

dont spouse you would fill me in on what the bold part below means im asuming the 190,190 are the distances from the taskarea marker. what are the -3

_armourgrp1 = [getmarkerpos "taskarea", east,["T72_TK_EP1", "BRDM2_ATGM_TK_EP1"],[[-3,-3], [190,190]]] call BIS_fnc_spawnGroup;
