    Step-by-step explanation:

    Cone Volume = 1/3 ×( π r² h)      h = 2 × diameter  =  2 × 2 × r

    Cone Volume = 1/3 ×( π r² h)      h = 2 × diameter    diameter = 2r

                                                           =  2 × (2 × r)  

                                                           = 4r

                                                             

    Cone Volume = 1/3 ×( π r² 4r)

                            =  (4 π r³ / 3)
