Question

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

Answer 1

I believe it’s 6 g/cm3. I hope this helps!

Answer 2

Answer:

A.$0.36 g/cm^3$

Step-by-step explanation:

We are given that

Mass of sphere =12 g

Radius of sphere=2 cm

We have to find the volume of sphere

We know that formula of sphere

Volume of sphere=$\frac{4}{3}\pi r^3$

Using this formula and substitute the values in the formula

Volume of sphere =$\frac{4}{3}\pi (2)^3=\frac{32}{3}\pi cm^3$

We know that

Density =$\frac{Mass}{volume}$

Density =$\frac{12}{\frac{32}{3}\pi}$

Density=$\frac{9}{8\times \frac{22}{7}}$

Using$\pi=\frac{22}{7}$

Density=$0.357 g/cm^3$

Density=$0.36 g/cm^3$

Therefore, option A is true.
