I NEED THIS ANSWER I DONT UNDERSTAND PLEASE HELP

Answer 1

A. 904.3 cm³

Explanation:

Radius of the ice cream cone (r) = 6 cm

Height of the ice cream cone (h) = 12 cm

Radius of the shape of hemisphere formed by the half scope of ice cream = 6 cm

Total volume of ice cream = volume of cone + volume of hemisphere

=
`((1)/(3) \pi r^2 h) + ((2)/(3) \pi r^3)`

Plug in the values

`((1)/(3) * 3.14 * 6^2 * 12) + ((2)/(3) * 3.14 * 6^3)`

`((1)/(3) * 3.14 * 36 * 12) + ((2)/(3) * 3.14 * 216)`

`= (1 * 3.14 * 12 * 12) + (2 * 3.14 * 72)`

`= (452.16) + (452.16)`

Total volume of ice cream = 904.3 cm³ (nearest tenth)
