Answer:40.0714286 m^3
Step-by-step explanation:common radius for all the solids=1.5 m
total length of the rocket=7m
height of the cone=2m
therefore height of the cylinder=7m-radius of the hemisphere-height of the cone
=7m-1.5m-2m
=3.5m
so, the volume of the rocket is
volume of cylinder+volume of hemisphere+volume of cone
=22/7x1.5x1.5x3.5 + 22/7x15.x1.5x1.5 + 1/3x22/7x1.5x1.5x2 m^3
=40.0714286 m^3
