Answer:

8. The volume of the rocket is
$105\pi$
.

Explanation:

8. The volume of the rocket = the volume of the cone + the volume of the cylinder.

The volume of the cone is =
$(1)/(3) \pi * radius^(2) (height) = (1)/(3) \pi * 3^(2) *5 = 15\pi$
inch^(3) .

The volume of the cylinder is
$\pi * radius^(2) * height = \pi * 3^(2) * 10 = 90\pi$
inch^(3) .

The total volume is
$15\pi + 90\pi = 105\pi inch^(3)$ .

9. Matt made the error in calculating the volume.

The diameter of the spherical ball is given by 15 centimeter.

The volume of a spherical ball is calculated by the formula
$(4)/(3) \pi * radius^(3)$ .

Matt put the diameter of the spherical ball instead of its radius.
