The volume of the 1 sphere is 37.68 cubic cm, for 2 the volume is 47646.87 cubic cm, for 3 the volume is 8751.46 cubic cm, and for 4 the volume is 3889.5 cubic cm and the mean is 15081.38.

<h3>What is a sphere?</h3>

It is defined as three-dimensional geometry when half-circle two-dimensional geometry is revolved around the diameter of the sphere that will form.

We know the volume of the sphere is the given by:

$\rm V = \dfrac{4}{3}\pi r^2$

For sphere 1 the radius r = 3 cm and π = 3.14

$\rm V = \dfrac{4}{3} \times3.14 (3)^2$

V = 37.68 cubic cm

For sphere 2: r = 42 in = 106.68 cm

$\rm V = \dfrac{4}{3} \times3.14 (106.68)^2$

V = 47646.87 cubic cm

For sphere 3: r = 18 in = 45.72 cm

V = 8751.46 cubic cm

For sphere 4: r = 1 ft = 30.48 cm

V = 3889.5 cubic cm

For the mean:

$=\rm \dfrac{37.68 +47646.87 +8751.46+3889.5 }{4}$

= 15081.3775 ≈ 15081.38

Thus, the volume of the 1 sphere is 37.68 cubic cm, for 2 the volume is 47646.87 cubic cm, for 3 the volume is 8751.46 cubic cm, and for 4 the volume is 3889.5 cubic cm and the mean is 15081.38.
