Nowadays,there are many kinds of shape but we can classify it into two groups which are regular and irregular shape but we choose to study in an irregular shape because it is so interesting and the shape that we want to study is “whirlpool”. From our research,there are 2 kinds of whirlpool,which are natural and force whirlpool which the force whirlpool can be made by using stirring machine then we take the photo of the whirlpool by its side After that we will find surface area of the whirlpool by making a model using a play dot then count the estimated area by using the value from the model.
