If the volume of a cone is 168 pi inches and its altitude is 14 inches, what is the radius of the cone? A. 36 inches B. 12 inches C. 72 inches D. 6 inches

The radius of the cone is 6 inches, which i mentioned in option D, for the volume of a cone is 168inches and its altitude is 14 inches.

Step-by-step explanation:

The given is.

         Volume of the cone is 168

         Altitude of the cone is 14 inches

Step:1

         Formula for Volume of cone is,

                     ....................................(1)

         Where,

                    V = 168 cubic inches

                      h = 14 inches

Step:2

          From the Eqn (1),

                     168 =                 (∵ Cancel   on both sides)

                        168 =

                  168 × 3 =

                       504 =

                            = 36

                             r =

                            r = 6 inches

Result:

      Thus the radius of the cone is 6 inches, If the volume of a cone is 168 pi inches and its altitude is 14 inches.

the fist one is not equalvalent but i think th second one isand the third isnt definetly or the last one is i think. hope this !
