Sara’s ice cream looks pretty normal. It is shaped like a cone topped with a half-sphere. The cone has a height of 9 in and a radius of 4 in.
What is the approximate volume of the whole shape? Round your answer to the nearest tenth. Use 3.14 to approximate pi. (Show your work.)

Respuesta :

Answer: 284.7

Step-by-step explanation:

radius of cone and hemisphere are the same

volume of half sphere=(1/2)*(4/3)*[tex]\pi r^{3}[/tex]

                                    =(1/2)*(4/3)*3.14*[tex]4^{3}[/tex]                       (4*4*4=64)

                                    =133.97333

                                    =133.97

volume of cone= (1/3)[tex]\pi r^{2}[/tex]h

                         =(1/3)*3.14*[tex]4^{2}[/tex]*9                                      (4*4=16)

                         =150.72

total volume=133.97+150.72

                    =284.69

                    =284.7
