    Well in doing these types of problems I sugest u sketch the regions and the area bounded by them u can then better visualze the volume of the region firn ur intersecting pooints of the two functions and always ask urswlf which way am I gnna tak slices in my region horizantally or verticcaly in this case it wid be easier to take dy as ur cuts and integrate that way try the problem now with the sketches Gud luck!!!
