Question

Find the amount of water displaced by a solid spherical ball of diameter
$28cm$

Answer 1

The volume of water displaced is the volume of the ball

$\begin{array}{c}V=\frac{4}{3}\pi r^{3}r=\frac{d}{2}\\ \Rightarrow \frac{4}{3}\times \frac{22}{7}\times 14\times 14\times 14\\ \Rightarrow 11498\frac{2}{3}c{m}^3\end{array}$
