Answer:

V_rocket  = 44[tex]\pi[/tex]  ft^3  = 138.2 ft^3

Step-by-step explanation:

Volume  of cone

V_cone = (1/3)*([tex]\pi[/tex]*(radius^2))*h

radius = 2ft

h = height of the cone = 3 ft

pi = 3.1416

V_cone = 4[tex]\pi[/tex]  ft^3

Volume cylinder

V_cylin = ([tex]\pi[/tex]*(radius^2))*h_cyl

h_cyl = height of the cylinder = 10 ft

V_cylin  = 40[tex]\pi[/tex]  ft^3

Volume rocket

V_rocket = V_cone  +  V_cylin  = 4[tex]\pi[/tex]  ft^3 + 40[tex]\pi[/tex]  ft^3

V_rocket  = 44[tex]\pi[/tex]  ft^3  = 138.2 ft^3
