Consider the volume of the solid generated by revolving the region bounded by the graphs of the equations about the line y = 7. 5 V= 1 +x Y = 0 X = 0 X = Using the washer method, find the outer radius R(x) and inner radius r(x). R(X) : 7 (7x + 2) r(x) = ( x + 1 ) Write and evaluate the definite integral that represents the volume of the solid. 5 (7x + 2)2 49 dx = (x + 1)2 X
