# Find the amount of water displaced by a solid spherical ball of diameteri) 28 cm ii) 0.21 m.

i)Given :
Radius of sphere = $$\frac{28}{2} cm = 14 cm$$

We know that,

Volume of sphere
= $$\frac{4}{3}{\pi}{r}^3$$
= $$\frac{4}{3} × \frac{22}{7} × {14}^3$$ $${cm}^3$$
= $$11498\frac{2}{3}$$ $${cm}^3$$

Therefore, the volume of the sphere is $$11498\frac{2}{3}$$ $${cm}^3$$.

ii)Given :
Radius of sphere = $$\frac{0.21}{2} m = 0.105 m$$

We know that,

Volume of sphere
= $$\frac{4}{3}{\pi}{r}^3$$
= $$\frac{4}{3} × \frac{22}{7} × {0.105}^3$$ $${m}^3$$
= $$0.004851$$ $${m}^3$$

Therefore, the volume of the sphere is $$0.004851$$ $${m}^3$$.
