Question

Find the volume of the largest right circular cone that can be cut out of a cube whose edge is 7 cm.

Answer 1

According to given sum$,$

Volume of cone$=\frac{1}{3}\pi r^{2}h$

Here$,$ height will be $7cm.$

and radius will be $\frac{7}{2}cm$

volume$=\frac{1}{3}\times \frac{22}{7}\times {\left(\frac{7}{2}\right)}^2\times 7$

$=89.83c{m}^2$
