Volume of a solid when revolved around a given line

Find the volumes of the solids generated by revolving the regions bounded by the graphs of the equations about the given lines.
y=sqr(6)
y=0
x=6

1.) the line x=6
2.) the line x=9

I'm having such issues with this question. Please please help me!

Nicole..be CAREFUL....I will assume it is y = √ x...{ √ is hold down alt which typing 251 ( windows)}

both are [ 2π radius height thickness ] integrations..over x in [ 0 , 6]

radius for1st is [ 6 - x] and 2nd [ 9 - x] , height is √x , thickness is [dx]


{ and 320π / 9 was correct for the typed problem }
