can somebody pretty plz help?? Use the method of cylindrical shells to find the volume generated by rotating the region bounded by the curves y = 3+2x-x^{2} and y+x=3 about the y-axis. Below is a graph of the bounded region. i graphed it and it turned out as a cone. area of cone = 1/3(pr r^2 h) but i dont know what the…

but i dont know what the radius is for the integral equation???
