Answer:

Height of the cone = 4 m

Explanation:

Given:

Volume of a cube = (12π) m^3

Radius of the cone = (6/2) m = 3 m

We have to find the value of "x".

And "x" is the height of the cone from the figure shown.

Formula to be used:

Volume of the cone: 1/3(πr^2h)

Here height = "x"


V_c_o_n_e=(\pi r^2 h)/(3)


V_c_o_n_e=(\pi r^2 x)/(3)


3* V_c_o_n_e=(\pi r^2 x)/(3)* 3


3* V_c_o_n_e=\pi r^2 x


(3* V_c_o_n_e)/(\pi r^2) =(\pi r^2* x)/(\pi r^2)


x=(3* V_c_o_n_e)/(\pi r^2 )


x=(3* 12\pi )/(\pi (3)^2 )


x=(36\pi )/(9\pi )


x=(36)/(9)


x=4 meters.

The height of the cone "x" = 4 meters option A is the right choice.
