When multiplying fractions, you multiply the denominators together and the numerators together.
3/8 x 4/9
(4•3)/(8•9)
12/72 = 1/6

1/6 is the final answer.

Answer:

V_rocket = 44 $\pi$ ft^3 = 138.2 ft^3

Step-by-step explanation:

Volume of cone

V_cone = (1/3)*( $\pi$ *(radius^2))*h

radius = 2ft

h = height of the cone = 3 ft

pi = 3.1416

V_cone = 4 $\pi$ ft^3

Volume cylinder

V_cylin = ( $\pi$ *(radius^2))*h_cyl

h_cyl = height of the cylinder = 10 ft

V_cylin = 40 $\pi$ ft^3

Volume rocket

V_rocket = V_cone + V_cylin = 4 $\pi$ ft^3 + 40 $\pi$ ft^3

V_rocket = 44 $\pi$ ft^3 = 138.2 ft^3
