Answer:
9/2π
=14.13716694
Step-by-step explanation:
The equation of the volume of the sphere:
V=4/3πr^3
If the diameter is 3cm, the radius is divided by 2, so 1.5cm.
Plug that in, 4/3π1.5^3
Use a calculator:
9/2π
=14.13716694
[tex]14,14~cm^{3}[/tex]
d = 3cm = 2r => r = d/2 = 3cm/2 = 1,5 cm
[tex]V=\frac{4}{3}\pi*r^{3}\\\\=\frac{4}{3}*\frac{22}{7}*3.375cm^{3}\\ \\=\frac{4*22*3.375}{21}cm^{3}\\ \\=\frac{297}{21}cm^{3}\\ \\[/tex]
≈ [tex]14,14~cm^{3}[/tex]
