Consider this composite figure made of a cone and a cylinder. A cone has a height of 8 centimeters and radius of 3 centimeters.
dangina [55]

The volume of cone is 75.4 cubic centimeters and the volume of cylinder is 197.92 cubic centimeters. The volume of composite figure is 273.32 cubic centimeters.

Step-by-step explanation:

The given is,

                Composite figure made of a cone and a cylinder.

                A cone has a height of 8 centimeters and radius of 3 centimeters.

                A cylinder has a height of 7 centimeters and radius of 3 centimeters.

Step:1

              Volume of composite figure = Volume of Cone +

                                                                 Volume of cylinder............(1)

Step:2

            Formula for volume of cone,

                   Volume of cone, V_{cone} = \pi r^{2} \frac{h}{3}....................(2)

           Where, r - Radius of cone

                       h - Height of cone

           From the given,

                            r = 3 centimeters

                           h = 8 centimeters

           Equation (2) becomes,

                                                   = \pi (3^{2} )(\frac{8}{3})

                                                   =\pi (9)(2.667)

                                                   = (3.14 × 9 × 2.667)           (∵ \pi = 3.1415)

                                                   = 75.4

                Volume of cone, V_{cone} = 75.4 cubic centimeters

Step:3

           Formula for volume of cylinder,

                   Volume of cone, V_{cone} = \pi r^{2} h....................(2)

           Where, r - Radius of cylinder

                       h - Height of cylinder

           From the given,

                            r = 3 centimeters

                           h = 7 centimeters

           Equation (2) becomes,

                                                   = \pi (3^{2} )(7)

                                                   =\pi (9)(7)

                                                   = (3.14 × 9 × 7)           (∵ \pi = 3.1415)

                                                   = 197.92

                Volume of cylinder, V_{cylinder} = 197.92 cubic centimeters

Step:4

         Equation (1) becomes,

            Volume of composite figure = 75.4 + 197.92

                                                            = 273.32 cubic centimeters    

Result:

           The volume of cone is 75.4 cubic centimeters and the volume of cylinder is 197.92 cubic centimeters. The volume of composite figure is 273.32 cubic centimeters.
