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.
What is a sphere?
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:
[tex]\rm V = \dfrac{4}{3}\pi r^2[/tex]
For sphere 1 the radius r = 3 cm and π = 3.14
[tex]\rm V = \dfrac{4}{3} \times3.14 (3)^2[/tex]
V = 37.68 cubic cm
For sphere 2: r = 42 in = 106.68 cm
[tex]\rm V = \dfrac{4}{3} \times3.14 (106.68)^2[/tex]
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:
[tex]=\rm \dfrac{37.68 +47646.87 +8751.46+3889.5 }{4}[/tex]
= 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.
