Find the area of the part of cylinder x^2 + y^2 = 2ay that lies outside the cone z^2 = x^2 + y^2.
@TuringTest Hi do you know how to do this question? thx a lot!
I'm a little unsure I did this right, do you know the answer?
|dw:1352831101743:dw|convert this to polar coordinates
@TuringTest the answer is 16a^2
i always got 8a^2, what i did is like using dS=zds and then use polar coordinates integrate from 0 to pi/2 and i got 4a^2 then multiply 2, so finally got 8a^2
and the graph for cylinder should be at the positive x axis
I seem to be messing this one up... I'll let you know if I make any progress.
