This week we studied finding volumes of solids created by rotating a formula on a certain interval around an axis or line, usually the x or y axis. It's a pretty speedy process! We are using the disk method and you basically take pi multiplied by the integral of the formula squared on the said interval. You just have to plug the integral into NINT and multiply the result by pi!! And that's not just pulled out of the air, it comes from the volume formula V= pi*hr^2. I can do the problems pretty quickly and easily which is a fun time! Hooray for understanding math!
