Answer:
A.[tex]0.36 g/cm^3[/tex]
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=[tex]\frac{4}{3}\pi r^3[/tex]
Using this formula and substitute the values in the formula
Volume of sphere =[tex]\frac{4}{3}\pi (2)^3=\frac{32}{3}\pi cm^3[/tex]
We know that
Density =[tex]\frac{Mass}{volume}[/tex]
Density =[tex]\frac{12}{\frac{32}{3}\pi}[/tex]
Density=[tex]\frac{9}{8\times \frac{22}{7}}[/tex]
Using[tex]\pi=\frac{22}{7}[/tex]
Density=[tex]0.357 g/cm^3[/tex]
Density=[tex]0.36 g/cm^3[/tex]
Therefore, option A is true.
