find the volume of the solids generated by revolving the regions bounded by the lines and curves about x-axis
y=square root cosx where 0 less than or equal to x less than or equal to pie/2 and y=0 x=0

$V = \int_0^{\frac{\pi}{2}}\pi y^2dx$

$= \pi\int_0^{\frac{\pi}{2}}\cos x dx$

Can you do it now?
