Consider the region of the xy plane between the line y=7, the curve y=3sinx+4, and for pi/2 is less than or equal to x which is less than or equal to pi/2.
Find the volume of the solid generated by revolving this region about the line .

Is it being rotated about the line y = 7 or y = 0 ?
If it is about y = 7, compute the integral of
pi*(3 sinx +4 7)^2 dx
= pi*(3 sinx 3)^2
between the two x limits
