A gigantic balloon used for a parade is shaped like an ice cream cone. The radius of the cone and the hemisphere is 12 feet. The height of the cone is 60 feet. If the balloon is filled with helium, how much helium will be needed to fill the balloon? Use 3.14 for pi.%0D%0A%0D%0A%0D%0A%0D%0APart A%0D%0A%0D%0AWhat is the volume of he hemisphere? Use 3.14 for pi and round your answer to the nearest tenth (one decimal place).s
The formula for the volume of a hemisphere is (2/3) * pi * r^3.
Given that the radius of the hemisphere is 12 feet, we can calculate its volume:
Volume = (2/3) * 3.14 * 12^3
= (2/3) * 3.14 * 1728
= (2/3) * 5418.24
= 3612.16 cubic feet
So, the volume of the hemisphere is approximately 3612.2 cubic feet.
