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

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