  • An ice cream cone full of ice cream having radius 5 cm and height 10 cm as shown in the Figure. Calculate the volume of ice cream, provided that its part is left unfilled with ice cream.

An ice cream cone full of ice cream having radius 5 cm and height 10 cm as shown in the Figure. Calculate the volume of ice cream, provided that its 1/8 part is left unfilled with ice cream.

In this figure, there is a hemisphere of radius of 5 cm

            And a cone of radius 5 cm and of height 10-5 = 5 cm

 Volume of cone

=\frac{1}{3}\pi r^2 h=\frac{1}{3}\times 3.14 \times (5)^2\times 5=130.83cm^3

            Volume of hemisphere

            =\frac{2}{3}\pi r^3

           =\frac{2}{3}\times 3.14 \times (5)^3=261.66cm^2

            The volume of complete figure = volume of cone + volume of the hemisphere

                        = 130.83 +261.66 = 392.49 cm^3

         \text{ The volume of the unfilled part }=\frac{392.49}{6}=65.41cm^3

            Volume of ice cream = volume of complete figure - volume of unfilled part

                                          392.49- 65.41=327.08 cm^3

            Hence the volume of ice cream is 327.08 cm3
