Use Array To apply eventListeners to numerous Buttons

I have this function that I want to apply to 10 different MovieClips that are on the stage by using an array. I wrote the array, I just need to know how I can apply the array to the function. Thank you

var sliceArray:Array=["slice1","slice2","slice3","slice4","slice5","slice6","slice7",
"slice8","slice9","slice10"];

btn1.addEventListener(MouseEvent.MOUSE_DOWN, sliderFunction)
btn1.addEventListener(MouseEvent.MOUSE_UP, sliderFunctionRelease)

function rotateMC(num:Number)
    {
        slice1.rotation+=num;       
    }

function sliderFunction(event:Event):void
    {
        stage.addEventListener(Event.ENTER_FRAME, onEnter)
    }

   
function onEnter(event:Event):void
    {
    rotateMC(10);
    }
   
function sliderFunctionRelease(event:Event):void
    {
        stage.removeEventListener(Event.ENTER_FRAME, onEnter);
    }
