Jackson buys a cherry snow cone on a hot day. What is the volume of "snow" he gets to eat? Use 3.14 for 1. Round your answer
3 cm
9 cm
98.9 cm
141.3 cm
O 155.4 cm
197.8 cm

Answer 1

Correct option: second one -> 141.3 cm3

Explanation:

To find the volume, we can calculate the volume of two separates parts (one half sphere and one cone) and then sum the volumes.

Volume of half sphere:

V1 = (2/3) * pi * r^3

The radius is 3 cm, so:

V1 = (2/3) * pi * 3^3 = 56.5 cm3

The volume of the cone is:

V2 = (1/3) * pi * r^2 * h

The radius is 3 cm and the height is 9 cm, so:

V2 = (1/3) * pi * 3^2 * 9 = 84.8 cm3

Then, the total volume is:

V = V1 + V2 = 56.5 + 84.8 = 141.3 cm3

Correct option: second one
