So here is the question
find the volume of the solid generated by revolving the region bounded by the curve y = sqrt(16 - x^2) and the line y = 0 about the x axis.
this is how I solved it
[tex] \int_{0}^{4} \Pi (16 - y^{2}) \; dy [/tex]
[tex] \Pi \int_{0}^{4} (16 - y^{2}) \; dy [/tex]
pi(16*y - y^3/3) from 0 to 4
pi(16*4 - 64/3 - 0)
so the answer I got is (128 pi)/3
is this correct.
