A:
Answer:V_rocket  = 44[tex]\pi[/tex]  ft^3  = 138.2 ft^3Step-by-step explanation:Volume  of coneV_cone = (1/3)*([tex]\pi[/tex]*(radius^2))*hradius = 2fth = height of the cone = 3 ftpi = 3.1416V_cone = 4[tex]\pi[/tex]  ft^3Volume cylinderV_cylin = ([tex]\pi[/tex]*(radius^2))*h_cylh_cyl = height of the cylinder = 10 ftV_cylin  = 40[tex]\pi[/tex]  ft^3Volume rocketV_rocket = V_cone  +  V_cylin  = 4[tex]\pi[/tex]  ft^3 + 40[tex]\pi[/tex]  ft^3V_rocket  = 44[tex]\pi[/tex]  ft^3  = 138.2 ft^3
