    Answer:

    option (b)

    Step-by-step explanation:

    as volume of the cone is πr²h/3= V

    therefore, when radius is doubled and height is tripled it would become:

                            π(2r)²3h/3  =  π4r²3h/3  =  12(πr²h/3)  =  12(V)

              hence it is 12 times of the volume.
