For class I had to measure an angle food cake pan using integration. The pan itself had a circular hole in the middle of it. So I figured I would take find the volume of the Large pan and then subtract the volume of the Small circular hole in the middle. As far as integration goes, I am kind of lost. I measured the pan and found the height to be 10cm, bottom radius to be 10.5cm and the top radius to be 14.25cm. The hole in the middle of the pan has a height of 10cm, bottom radius of 3cm and a top radius of 2cm. I figured I would use the integration of a frustum of a cone around the y-axis but I am having a big trouble setting it up. Any help would be appreciated.
