Q:
Find the volume V of the solid obtained byrotating the region bounded by the given curves about the specifiedline.
y = x + 1, y =0, x = 0, x = 4 aboutthe x-axis
V = ?, Sketch the region, Sketch the solid and atypical disk or washer.
2- Find the volume V of the solidobtained by rotating the region bounded by the given curves aboutthe specified line.
y =
, y =0, x = 5; aboutthe x-axis
V = ?, Sketch the region, Sketch the solid and atypical disk or washer.
