Answer:

height =45 cm

diameter of upper end =56 cm

radius (r₁)=28 cm

diameter of lower end = 14 cm

radius (r₂)=7 cm

volume of frustum of cone = 1/3πh(r₁²+r₂²+r₁r₂)

                                             =1/3×22/7×45(28²+7²+28×7)

                                             =1/3×22/7×45(784+49+196)

                                              = 1/3×22/7×45(1029)

                                              =1018710/21

                                              = 48510
