I need help with these problems.

Find the volume of the solid obtained by rotating the region bounded by the given curves about the specified axis. $$y=0,y=x(1?x)$$ about the axis $$x=0$$ Area Volumes: Problem 6 (1 point) Find the volume of the solid obtained by rotating the region bounded by the given curves about the specified axis. $$y=6x^2,x=1,y=0$$, about the $$\mathrm{x}$$-axis Area Volumes: Problem 3 (1 point) Find the area of the region between the curves $$y=\sin (x),y=e^x,x=0$$, and $$x=?/2$$.
