Ice cream is put into a waffle cone so it fills the cone to the top.
The volume, `V`, of the cone is given by the rule `V = (pir^2h)/3`,
where `r` is the radius of the cone in centimetres and `h` is the height in centimetres.
When `h = 12` and `r = 3`, the volume of the cone is closest to
`38\ text(cm)³` | `113\ text(cm)³` | `339\ text(cm)³` | `452\ text(cm)³` |
