Answer:
begin mathsize 16px style straight H equals Height space of space the space cylinder
straight R equals radius space of space the space cylinder
straight h equals height space of space cone space
straight r equals radius space of space cone
straight V equals Volume space of space cylinder minus Volume space of space cone minus Volume space of space hemisphere
straight V equals πR squared straight H minus 1 third πr squared straight h minus 2 over 3 πr cubed
straight R equals 3 space cm comma space straight H equals 6 space cm comma space straight r equals 2 space cm comma space straight h equals 4 space cm
Put space it space in space the space above space formula space we space get space
straight V equals 136 space cm cubed end style
