Question

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

Answer 1

Answer:

$\huge{\underline{\underline{\mathcal{\orange{Answer}}}}}$

(0.36 g/cm^3.

Answer 2

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

Density = Mass/volume

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

Volume of a sphere is given by the formula

V = 4/3πr³

Where VV is the volume of the sphere

and rr is the radius of the sphere

Take π=3.14159

From the question, r = 2 cm

Put these values into the equation,

V=33.51029 cm³

Density=0.3581 g/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)
