Adding some actions.

Move Movie Clip - Flower to place on Movie Stage where You want your flower to be drawn.(normally, it's a center of Movie (Document) Stage)

Now You have knowledge about polar coordinates to draw a flower. You just need to program it. I have done it for You. Select flower on the stage ( just mouse left-click on MovieClip ) and press F9 to bring up it's actions. Put this actions (if you want just paste this actions you should turn to Expert Mode before.)

onClipEvent (load) {
	amp = 160; // sets amplitude of flower's petal.
	x0 = 0; y0 = 0	; // set coordinates where flower should be drawn. in Movie Clip
	// zero values recommended.
	// if want to draw flower in another place just drag Movie Clip - "flower"  on Movie Stage 
	moveTo(x0+amp, y0); // go to a start point.
	degree = 0;	 // degree sets angel used in polar coordinates. 
	speedDraw = 1;	// sets how fast flower will be drawn. value must be set with natural number. 
	// for example: 1,2,4...
	colorFlower = 0x009933; // green 
	colorCircle = 0xEBEA2E; // yellow
	lineStyle(3, colorFlower, 100); // sets line style.
}
// Below we draw flower.
onClipEvent (enterFrame) {
	if (degree<=360) { 
		for (i=1; i<=speedDraw; i++) {
			radian = Math.PI/180*(degree);
			p = amp*Math.cos(6*radian); // flower determinated in  polar coordinates
			x = x0+p*Math.cos(radian); // convert polar coordinates  to Cartesian one.
			y = y0+p*Math.sin(radian); // -//-
			lineTo(x, y); // draw line
			degree++; 
		}
	}
}
// Here is drawing  circle that is in the flower center.
onClipEvent (enterFrame) {
	if (degree == 360+speedDraw) { //starts draw circle after flower have bee drawn.
		amp = 10; 
		x0 = x0-amp/2;
		y0 = y0;
		moveTo(x0, y0);
		lineStyle(1, colorCircle , 100);
		beginFill(colorCircle); // The circle must be filled. So we start filling here.
		for (alpha=0; alpha<=180; alpha++) {
			radian = Math.PI/180*(alpha); // circle determinated in  polar coordinates
			p = amp*(Math.cos(radian));
			x = x0+p*Math.cos(radian);
			y = y0+p*Math.sin(radian);
			lineTo(x, y);
		}
		endFill(); // end of filling.
		degree++;
	}
}
