a sphere with a mass of 12 g has a radius measuring 2 cm. what is its density?

0.36 g/cm3
1.43 g/cm3
6 g/cm3
24 g/cm3

The density of the sphere with mass 12 g and radius 2 cm is 0.36 g/cm³. The correct option is the first one (0.36 g/cm3)

From the question,

The mass of the sphere is 12 g and

The radius is 2 cm.

To determine its density,

From the formula

Therefore, we will first determine the volume of the sphere.

Volume of a sphere is given by the formula

Where is the volume of the sphere

and is the radius of the sphere

Take

From the question,

Put these values into the equation,

Now, for the density

Put the values of the volume and mass in the equation

From the question, mass = 12 g

From above, V = 33.51029 cm³

∴

Density ≅ 0.36 g/cm³

Hence, the density of the sphere with mass 12 g and radius 2 cm is 0.36 g/cm³. The correct option is the first one (0.36 g/cm3)
