Answer:
Step-by-step explanation:
A. 0.36 g/cm³
Explanation:
Density = mass/volume
We know the mass, but we must calculate the volume.
The formula for the <em>volume of a sphere</em> is
V = ⁴/₃πr³
r = 2 cm
V = ⁴/₃π × 2³
V = (4π×8)/3
V = (32π)/3
V = 33.5 cm³
=====
Calculate the <em>density
</em>
Density = 12/33.5
Density = 0.36 g/cm³
The density of the sphere is 0.36 g/cm³.
