**Radius = 0.18 cm**

**Density = 2.7 g/cc**

**Volume of the sphere = 4/3πr**³

**V = 4/3*0.18*0.18*0.18*22/7**

**V = 0.024 cc**

**Therefore mass,**

**Density = mass/volume**

**2.7 = m / 0.024**

**M = 0.0648 g**

**I hope it helps………..**

**Radius = 0.18 cm**

**Density = 2.7 g/cc**

**Volume of the sphere = 4/3πr³**

**= 4/3 x 22/7 x 0.18 x 0.18 x 0.18**

**V = 0.024 cc**

**so,**

**Density = mass/volume**

**2.7 = m / 0.024**

**m = 0.0648 g**
