Answer:

Half of 6 is 3(new radius)

3^3 = 9

9 x 3.14 = 28.26(area of circle)

Now we multiply by height

28.26 x 5 = 141.3

Now we divide by 3 since its part for the formula of finding the cone's volume:

141.3 x 1/3(basically just dividing by 3) = 47.1

Now let's find the volume of the cylinder:

3^3 = 9, 9 x 3.14 = 28.26

28.26 x 14 = 395.64

Now let's add the given volumes:

395.64 + 47.1 = 442.74 cm^3 is your answer.
