It is given in the question that the solid is a cone with height of 16 units and radius of 7 units .
The formula of volume of cone is
[tex]V = \frac{1}{3} \pi r^2 h[/tex]
To find the volume, we substitute the given values of r and h and use 3.14 for pi. That is
[tex]V = \frac{1}{3} *3.14*7^2 *16 = 820.6 \ units \ cube[/tex]
And that's the required volume of the cone .
