Give examples of the following: - homologous structures - analogous structures - vestigial structures

Homologous- Bat's wing or a dolphin's flipper
Analogous- The similarites in bone structure between a shark's fin, a penguin's wing and a dolphin's flipper
Vestigial- Whale's hind legs or an ostrich's wings

See diagram.we use washers to get the area and we will be integrating with respect to xouter radius is the  distance between y = e^x and y = -1    inner radius of washer is the distance between y = 1 and y = -1    the area of one cross-section of a washer is    solid lies between x = 0 and x = 2. the volume is    if you need this expanded, then    the question doesn't say to evaluate, so we're done.
