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 [tex]r=\frac{d}{2}[/tex]
[tex]r=\frac{50}{2}=25\ feet[/tex]
The air does it contain is given by the volume of the ball.
The volume of the ball is [tex]V=\frac{4}{3}\pi r^3[/tex]
[tex]V=\frac{4}{3}\times 3.14\times (25)^3[/tex]
[tex]V=\frac{4}{3}\times 3.14\times 15625[/tex]
[tex]V=65416.67\ ft^3[/tex]
Therefore, the balloon contain 65416.6 cubic feet.
