In order to calculate the volume of a cone, we can usethe formula blelow:
Where r is the base radius and h is the cone's height.
So, using the given values, we have:
![\begin{gathered} V=(1)/(3)\cdot3.14\cdot49^2\cdot62\\ \\ V=155808.89\text{ m^^b3} \end{gathered}]()
Then, if 1 meter is equal to 3.2808 ft, the conversion to cubic foot is given by:
![155808.89\cdot(3.2808)^3\text{ ft^^b3}=5,502,138.41\text{ ft^^b3}]()
Therefore the correct option is the fourth one.
