To calculate the volume of the balloon, we need to find the volume of the cone and the volume of the hemisphere separately, and then add them together.
The volume of a cone is given by the formula V_cone = (1/3) * pi * r^2 * h, where r is the radius and h is the height.
Plugging in the values, we have V_cone = (1/3) * 3.14 * 12^2 * 60 = 30144 cubic feet.
The volume of a hemisphere is given by the formula V_hemisphere = (2/3) * pi * r^3.
Plugging in the values, we have V_hemisphere = (2/3) * 3.14 * 12^3 = 904.32 cubic feet.
Adding the volumes of the cone and hemisphere together, we have V_total = V_cone + V_hemisphere = 30144 + 904.32 = 31048.32 cubic feet.
Therefore, approximately 31048.32 cubic feet of helium will be needed to fill the balloon.
A giant balloon used for a parade is shaped like a ice cream cone. The radius of the cone and the hemisphere is 12 feet. The height of the cone is 60 feet it’s a balloon is filled with humanism. How much humanism will be needed to fill the balloon use 3.14 for pi.
