Answer:
The balloon contain 65416.6 cubic feet.
Step-by-step explanation:
Given : If you have a round hot air balloon that is shaped like a ball and is 50 feet in diameter.
To find : How much air does it contain?
Solution :
The ball is in spherical shape.
The diameter d=50 feet.
The radius is ![r=\frac{d}{2}](https://tex.z-dn.net/?f=r%3D%5Cfrac%7Bd%7D%7B2%7D)
![r=\frac{50}{2}=25\ feet](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B50%7D%7B2%7D%3D25%5C%20feet)
The air does it contain is given by the volume of the ball.
The volume of the ball is ![V=\frac{4}{3}\pi r^3](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3)
![V=\frac{4}{3}\times 3.14\times (25)^3](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B4%7D%7B3%7D%5Ctimes%203.14%5Ctimes%20%2825%29%5E3)
![V=\frac{4}{3}\times 3.14\times 15625](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B4%7D%7B3%7D%5Ctimes%203.14%5Ctimes%2015625)
![V=65416.67\ ft^3](https://tex.z-dn.net/?f=V%3D65416.67%5C%20ft%5E3)
Therefore, the balloon contain 65416.6 cubic feet.
