Question

Find the volume of largest sphere covered out of a cube of side $7cm$.

Answer 1

$\begin{array}{c}Diameterofsphere=7cm\\ \Rightarrow volumeofsphere=\frac{4}{3}\pi r^3\\ \Rightarrow Volume=\frac{4}{3}\times \frac{22}{7}\times \frac{7}{2}\times \frac{7}{2}\times \frac{7}{2}=\frac{11\times 49}{3}=179.66c{m}^3\\ \Rightarrow 179.66c{m}^3\end{array}$
