I submitted this earlier and received only decimal answers even though it specifically states exact answers are required (SEE PART A ANSWER FORMATTING). Also parts B-D of the answers from my last tutor were unfortunately wrong. Part A was marked correct but could someone take a stab at parts B-D again for me? I am no less stuck and am not sure how to do it so any help would be great.

(BECAUSE NOT VISIBLE TO FIT ALL PARTS IN SCREENSHOT, PARTS C/D ARE AS OLLOWS:

C. Rotated w respect to the line x= -7

D. Rotated w respect to the line y= -7

Use the region in the rst quadrant bounded by the x-axis and the graph of y = xVS x. Find the volume of a solid of revolution generated by revolving this region about the x-axis. (Give answer in exact form. Use symbolic notation and fractions where needed.) 625?: volume: 1 2 Find the volume of a solid of revolution generated by revolving this region about the yaxis.
