$V =\frac{1}{3} \pi r^2 h$

For this case we know that the radius is r=7cm and the height is h =11cm. And replacing we got:

$V=\frac{1}{3} \pi (7cm)^2 (11cm)= \frac{1}{3} \pi (49cm^2) (11 cm)=\frac{539}{3} \pi cm^3$

And the best option would be:

$V = \frac{539}{3} \pi cm^3$

Step-by-step explanation:

For this case we know that the volume of the cone is given by:

$V =\frac{1}{3} \pi r^2 h$

12 units

Step-by-step explanation:

Because the two triangles are similar:

$\dfrac{x}{9}=\dfrac{16}{x} \\\\\\\dfrac{x^2}{9}=16 \\\\\\x^2=144 \\\\\\x=12$

Hope this helps!
