Question
Ariah has a hot air balloon. When full, the
balloon is a sphere with a radius of 9 meters.
She fills it with hot air whose density is 0.9
kilograms per cubic meter. Since this is less
dense than the air in the atmosphere, the
balloon is carried upwards.
What is the weight of the air that Ariah
needs to fill the balloon?
Round your answer, if necessary, to the
nearest integer.

To find the weight of the air that Ariah needs to fill the balloon, we first calculate the volume of the balloon using the formula for the volume of a sphere:
Substituting the radius
Next, we can find the weight of the air by multiplying the volume by the density:
Rounding to the nearest integer, the weight of the air that Ariah needs to fill the balloon is approximately 2748 kg.
