what is the volume of the item described? an ice cream cone with a cone of radius 2 cm and height of 9 cm with a hemisphere of ice cream on top of radius 2 cm. select the exact answer in terms of π and the approximate answer rounded to the nearest whole number. 683π cm³ 54 cm³ 71 cm³ 147 cm³ 1403π cm³ 523π cm³
pick 2

➷ Formula for volume of cone:

1/3

Substitute the values in:

1/3

Leave it in terms of pi:

volume of the cone = 12

A hemisphere is half of a sphere so we use the formula for volume of a sphere and halve it.

volume of hemisphere = (4/3) / 2

Substitute the values in:

(4/3) / 2

Leave it in terms of pi:

volume of the hemisphere = 16/3

Now add the two volumes together:

12 + 16/3 = 52/3

The two answers would be : 52/3 cm^3 and 54 cm^3
