Find the volume of right circular cone having base diameter 16 cm and height 15 cm.

We have given that,

Height of cone =15 cm and base diameter =16 cm

Then, r = $\frac{16}{2}=8 \mathrm{cm}$

We know that,

The volume of the right circular cone = $\frac{1}{3}{\mathrm{\pi r}}^2\mathrm{h}$

                                                 =    $\frac{1}{3}\times \mathrm{\pi }\times 8\times 8\times 15 =320\mathrm{\pi } {\mathrm{cm}}^3$
