$?=x\\\\\frac{9}{11}=\frac{x}{22}\ \ \ |it's\ a\ proportion\ \ \ |cross\ multiply\\\\11\cdot x=9\cdot22\ \ \ \ |divide\ both\ sides\ by\ 11\\\\x=\frac{9\cdot\not22^2}{\not11_1}\\\\x=\frac{9\cdot2}{1}\\\\\boxed{x=18}

The question mark will be 18 as
the denominator x 2 (11 x 2 = 22) so 9 x 2 = 18

Answer: We have to find the volume of a sphere, provided its radius:

$R_{sphere}=13\operatorname{cm}$

The formula for sphere volume is:

$V_{sphere}=\frac{4}{3}\pi R^3$

Therefore now we can find the volume, because we have the value of the Radius of the sphere, and we do it next.!

$\begin{gathered} R_{sphere}=13\operatorname{cm} \\ \rightarrow\therefore\rightarrow \\ V_{sphere}=\frac{4}{3}\pi(13\operatorname{cm})^3=\frac{4}{3}\pi2197\text{ cm}^3 \end{gathered}$

Simplification gives:
