Given that
The figure is of a cone and we have to find the volume of the cone.
Explanation -
The diameter of the cone is 22km and the height is also 22 km.
So the radius will be
radius = r = d/2 = 22/2 km = 11 km
Hence, r = 11 km and h = 22 km
The formula for the volume of the cone will be
[tex]Volume=\frac{1}{3}\times\pi\times r^2h[/tex]
On substituting the values we have
[tex]\begin{gathered} V=\frac{1}{3}\times\pi\times11^2\times22\text{ km}^2 \\ \\ V=\frac{1}{3}\times\frac{22}{7}\times11\times11\times22\text{ km}^2 \\ \\ V=\frac{58564}{21}\text{ km}^2=2788.7\text{ km}^2 \end{gathered}[/tex]
So B is the correct option.
Final answer -
Hence the final answer is 2788 sq km.
