\fFind the area bounded by the given curves, axes and/or lines a. y23x+3=Oandx =4 b. y2 = x , y = x C. y=9x2,y=x+3 Find the volume generated when the area is rotate about the given axis or line: y = 9 x2 and y = 0, rotated about x axis use two methods. Referring to number #2, nd the centroid about the x and y axis
