$Default$ Inegration and volumes

Use the washer method to find the volume of the solid obtained by revolving the region between y = (x^2) and y = 4x about the x -axis.

My answer basically came out to be around = (135)(pi)

I don't have answers in my book to double check it. Any help would be appreciated.
