1. Find the volume of the solid generated by revolving the region inside the circlex²+y²=4and to the right of the linex=1about they-axis.

2. Find the volume of the solid generated by revolving the region enclosed by the curves

(7/3)*y=e^8x,x=0, and y=3*e^(7/3) about the x-axis.

Please guide me through how to solve those problems, thanks.
